Abstract
In the anion of the title compound, (C12H13N2)[Ni(C4N2S2)2], the NiII atom is coordinated by four S atoms from two 1,2-dicyanoethene-1,2-dithiolate (mnt) ligands in a suqare-planar geometry. Weak C—H⋯N and C—H⋯S hydrogen bonds between the 1-ethyl-4,4′-bipyridin-1-ium cations and mnt anions and weak π–π interactions between the pyridine rings of the cations [centroid–centroid distances = 3.808 (3) and 3.972 (3) Å] lead to a two-dimensional network parallel to (010).

Abstract
In the title ion-pair complex, (C12H14N2)[Cu(C4N2S2)2], the complex anion exhibits a highly twisted coordination environment around the tetra-coordinated Cu(II) atom. The dihedral angles between the 1,2-di-cyano-ethene-1,2-di-thiol-ato ligands and between the two pyridine rings in the cation are 37.49 (3) and 29.18 (10)°, respectively. Weak C-H⋯N and C-H⋯S hydrogen bonds link the cations and anions into a three-dimensional network.

Abstract
A new one-dimensional (1-D) ion-pair compound, [1,7-bis(1-methylimidazolium)heptane][Ni(mnt)(2)](2) (mnt(2-) = maleonitriledithiolate), was synthesized and characterized structurally and magnetically. This compound shows a spin-Peierls-type transition at around 235 K. Its crystal structure belongs to the monoclinic system with space group C2/c and the magnetic [Ni(mnt)(2)](-) anions form uniform stacks in the high-temperature (HT) phase. The crystal undergoes a transformation into the triclinic space group P1 accompanied by the magnetic transition and the anion stacks become dimerized in the low-temperature (LT) phase. The entropy changes (ΔS) are estimated to be 0.772 J K(-1) mol(-1) for the spin-Peierls-type transition, from DSC data, which is much less than the spin entropy change (ΔS = R ln 2 ≈ 5.76 J K(-1) mol(-1)), indicating that a substantial short-range order persists above the transition temperature. The variable temperature IR spectra showed that the peak positions and intensities for the bands near 1160 and 725 cm(-1), which correspond respectively to the ν(C-C) + ν(C-S) mode of the mnt(2-) ligands and the rocking vibration mode of the methylene group γ(r)(CH(2)) in the cation moiety, undergo an abrupt change at around 240 K, close to the transition temperature. This observation demonstrates that the intramolecular vibrations of both the anion and the counter-cation probably couple with the spins to cooperate with the spin-Peierls-type phase transition in this 1-D spin system.

Abstract
Four new 1D spin-Peierls-type compounds, [D(5)]1-(4'-R-benzyl)pyridinium bis(maleonitriledithiolato)nickelate ([D(5)]R-Py; R=F, I, CH(3), and NO(2)), were synthesized and characterized structurally and magnetically. These 1D compounds are isostructural with the corresponding non-deuterated compounds, 1-(4'-R-benzyl)pyridinium bis(maleonitriledithiolato)nickelate (R-Py; R=F, I, CH(3), and NO(2)). Compounds [D(5)]R-Py and R-Py (R=F, I, CH(3), and NO(2)) crystallize in the monoclinic space group P2(1)/c with uniform stacks of anions and cations in the high-temperature phase and triclinic space group P1 with dimerized stacks of anions and cations in the low-temperature phase. Similar to the non-deuterated R-Py compounds, a spin-Peierls-type transition occurs at a critical temperature for each [D(5)]R-Py compound; the magnetic character of the 1D S=1/2 ferromagnetic chain for [D(5)]F-Py and the 1D S=1/2 Heisenberg antiferromagnetic chain for others appear above the transition temperature. Spin-gap magnetic behavior was observed for all of these compounds below the transition temperature. In comparison to the corresponding R-Py compound, the cell volume is almost unchanged for [D(5)]F-Py and shows slight expansion for [D(5)]R-Py (R=I, CH(3), and NO(2)) as well as an increase in the spin-Peierls-type transition temperature for all of these 1D compounds in the order of F>I≈CH(3)≈NO(2). The large isotopic effect of nonmagnetic countercations on the spin-Peierls-type transition critical temperature, T(C), can be attributed to the change in ω(0) with isotope substitution.

Abstract
The crystal structures and magnetic properties were investigated experimentally and theoretically for two S = ½ spin chain complexes, which consist of [M(mnt)(2)](-) (M = Pt for 1 or Pd for 2) with 1-(4'-bromo-2'-flurobenzyl)-4-aminopyridinium (1-BrFBz-4-NH(2)Py(+)). The 1-BrFBz-4-NH(2)Py(+) cations exhibit different molecular conformations and arrangements in 1 and 2; the [M(mnt)(2)](-) anions form regular stacks in 1, whereas they form irregular stacks in 2. In addition, the intermolecular interactions between the [M(mnt)(2)](-) anions and cations are also different from each other in the crystals of 1 and 2. Complex 1 shows the magnetic characteristics of a low-dimensional antiferromagnetic coupling spin system with a spin-Peierls-type transition around 7 K, and complex 2 exhibits diamagnetism over the temperature range of 5-300 K. Theoretical analyses, based on the calculations for the charge density distributions of [Pt(mnt)(2)](-) and [Pd(mnt)(2)](-) anions and the magnetic exchange constants within the anion spin chains, addressed the diverse molecular alignments in the crystals of 1 and 2 and distinct magnetic behaviors between 1 and 2.

Abstract
The title ion-pair compound, (C7H7N2)2[Cu(C4N2S2)2], was obtained by the direct reaction of CuCl2·2H2O, disodium maleonitriledithiolate (Na2mnt) and 4-cyano-1-methylpyridinium iodide. The anion and one pyridinium cation lie entirely on a mirror plane, whereas for the other cation, a crystallographic mirror plane runs through the N and para-C atoms of the pyridine ring, the methyl C atom, and the cyano group. In the crystal, ions are linked into a three-dimensional network by C—H⋯N hydrogen bonds.

Abstract
Two deuteriumed quasi-one-dimensional (quasi-1D) spin-Peierls-type compounds, 4-X-benzylpyridinium-d(5) bis(maleo-nitriledithiolato)nickelate (the substituent X = Br or Cl), were structurally characterized. Compared with the corresponding non-deuteration compounds, the transition temperature T(C) shifts to higher temperature. The isotopic effect of countercations on T(C) is probably related to the change of phonon frequency ω(0) and 'chemical pressure' resulted from the substitution of pyridine by pyridine-d(5).

Abstract
The asymmetric unit of the title complex, (C12H10N3)2[Ni(C4N2S2)2], consists of one 1-(4-cyanobenzyl)pyrazinium cation and one half of an [Ni(mnt)2]2− dianion (mnt2− is 1,2-dicyanoethene-1,2-dithiolate). The Ni2+ ion is located on an inversion center and is coordinated by four S atoms from two mnt2− ligands, exhibiting a square-planar coordination geometry. The cation adopts a conformation where both the pyrazine ring and the benzene ring are twisted with respect to the C—C—N reference plane by 16.5 (2) and 69.8 (1)°, respectively.

Abstract
The asymmetric unit of the title complex, (C6H13N4)2[Ni(C4N2S2)2], comprises one 1-azonia-3,5,7-triazatricyclo[3.3.1.13,7]decane cation and one half of an [Ni(mnt)2]2− (mnt2− is maleonitriledithiolate or 1,2-dicyanoethene-1,2-dithiolate) dianion. The Ni2+ ion is located on a center of inversion and is coordinated by four S atoms from two mnt2− ligands in a square-planar coordination mode. Intermolecular N—H⋯N hydrogen-bond interactions link one anion and two cations in the crystal structure.
