Crystal structure of catena-poly[[[bis-(pyridine-4-carbo-thio-amide-κN (1))cadmium]-di-μ-thio-cyanato-κ(2) N:S;κ(2) S:N] methanol disolvate]

Cu(i) Iodide coordination polymers with aromatic thioamides

The reaction of 4-pyridinethiobenzamide (PyTBA) with CuI and KI aqueous solution in acetone or THF under slow diffusion gives rise to the formation of single crystals of two coordination polymers [CuIPyTBA]_n·nS (S = acetone; 1/3THF).

Reaction of Co(NCS)2 or Ni(NCS)2 with pyridine-4-thio-amide in different solvents led to the formation of two compounds with composition [Co(NCS)2(C2H3N)(C6H6N2S)3]·2CH3CN (1) and [Ni(NCS)2(C6H6N2S)4]·5CH3OH (2), respectively. The asymmetric unit of compound 1 consists of one cobalt(II) cation, two thio-cyanate anions, three pyridine-4-thio-amide ligands, one coordinating and two solvate aceto-nitrile mol-ecules. One of the two aceto-nitrile solvate mol-ecules is disordered over two sets of sites in a 0.62:0.38 ratio. The asymmetric unit of compound 2 comprises of one nickel(II) cation, two thio-cyanate anions, four N-bonding pyridine-4-thio-amide ligands and five methanol solvate mol-ecules. In compound 1, the cobalt(II) cations are octa-hedrally coordinated into discrete complexes by two terminal N-bonding thio-cyanate anions, the N atoms of three pyridine-4-thio-amide ligands and one aceto-nitrile mol-ecule. Additional aceto-nitrile solvate mol-ecules are located between the complexes,. The complexes and solvate mol-ecules are linked via inter-molecular hydrogen bonding into a three-dimensional framework. In compound 2, the nickel(II) cations are likewise octa-hedrally coordinated by two terminal N-bonded thio-cyanate anions and four N-bonding pyridine-4-thio-amide ligands into discrete complexes. From their arrangement cavities are formed, in which the methanol solvate mol-ecules are located. Again, the complexes and solvate mol-ecules are linked into a three-dimensional framework by inter-molecular hydrogen bonding.

Crystal structure of bis-(pyridine-4-carbo-thio-amide-κN1)bis-(thio-cyanato-κN)cobalt(II) methanol monosolvate

The asymmetric unit of the title compound, [Co(NCS)2(C6H6NS)4]·CH3OH, consists of one cobalt(II) cation, two thio-cyanate anions, four pyridine-4-carbo-thio-amide ligands and one methanol mol-ecule that are located in general positions. The CoII cations are coordinated by two terminal N-bonding thio-cyanate anions and four N-bonding pyridine-4-carbo-thio-amide ligands, resulting in discrete and slightly distorted octa-hedral complexes. These complexes are linked into a three-dimensional network via inter-molecular N-H⋯S hydrogen bonding between the amino H atoms and the thio-cyanate and pyridine-4-carbo-thio-amide S atoms. From this arrangement, channels are formed in which the methanol solvate mol-ecules are embedded and linked to the host structure by inter-molecular O-H⋯S and N-H⋯O hydrogen bonding.
