Three iodocuprate hybrids symmetrically modulated by positional isomers and the chiral conformation of N-benzyl-methylpyridinium

The successful synthesis and structural analysis of three novel iodocuprate frameworks, [N-Bz-2-MePy]₂[Cu₅I₇] (1), [N-Bz-3-MePy]₂[Cu₅I₇] (2), and [N-Bz-4-MePy][Cu₄I₅] (3), exhibit an excellent structural directing effect of the conformationally chiral N-Bz-MePy⁺.

Symmetrically Related Construction and Optical Properties of Two Noncentrosymmetric 3D Iodides of d(10) Cation (Cu(+), Ag(+)) Based on the N-Benzylpyridinium and Its Supramolecular Interactions

Two noncentrosymmetric compounds, namely, [N-Bz-Py]2[Cu6I8] (1) and [N-Bz-Py]4[Ag9I13] (2) (N-Bz-Py(+) = N-benzylpyridinium), with three-dimensional open frameworks, were synthesized solvothermally via in situ benzylation of pyridine. 1 is constructed from 3-connected Cu3I7 secondary building units (SBUs) with chiral (10,3)-a topology, while the occluded N-Bz-Py(+) forms a complementary supramolecular (10,3)-a net via π-π interactions. 2 is characteristic of acentric connections of trimeric Ag3I8 and hexamer Ag6I12 SBU, while N-Bz-Py(+) in the channels aggregates into asymmetrically supramolecular chains via π-π interactions. Remarkable structural correlations imply the unique amplification and transfer of asymmetric information from V-shaped N-Bz-Py(+) to organic supramolecular nets and inorganic frameworks, which are confirmed by their second harmonic generation responses. Adsorption spectra reveal their semiconductive nature (2.52 eV for 1 and 3.02 eV for 2) and interesting reversible thermochromism for 1 based on the intermolecular charge transfer.

The newly synthesized compounds have been characterized by elemental analysis, UV-Vis spectrometry, IR spectroscopy, thermogravimetry analysis, solid state (31)P MAS NMR, powder X-ray diffraction analysis and single crystal X-ray diffraction techniques. The single crystal structure analysis revealed structural variability of the prepared compounds. Compounds 1, 2, 4 and 5 are three-dimensional with the H2PMIDA skeletons connecting the inorganic parts to each other, whereas compound has a layered structure. Compounds 2, 4 and 5 contain helical structural motifs. In addition, the extrinsic luminescent properties of Eu(III)- and Tb(III)-doped compounds 1, 4 and 5 have also been studied.

New Titanium and Nickel Gallophosphates with Layered Structures

Two new transition-metal gallophosphates, (H(2)C(4)H(10)N(2))(3)[(Ti(2.5)(H(2)O)(4)Ga(5.5)(PO(4))(10)].2H(2)O (TGP-1) and [H(3.5)(C(4)H(13)N(3))(2)][(Ni(0.5)(OH)(4)Ga(5.5)(PO(4))(3)(HPO(4))(4)].2H(2)O (NGP-1), have been synthesized under mild hydrothermal conditions and characterized by single-crystal X-ray diffraction, thermogravimetric analysis, electron paramagnetic resonance, electron probe microanalysis, and magnetic susceptibility data. TGP-1 exhibits a unique two-dimensional structure consisting of tetrahedral and octahedral metals centers and is the foremost paramagnetic TiGaPO material ever prepared. NGP-1 as well represents the first NiGaPO compound and adopts a layer structure that is constructed from hexameric M-O clusters of trigonal bipyramids and octahedra. In both compounds, the transition metals incorporate with gallium into octahedral sites only, while the four- and five-coordinated metals centers are only Ga(3+) ions. The unique sites for Ti(3+) and Ni(2+) ions have been initially elucidated from single-crystal structure refinements and further confirmed by bond-valence-sum calculations, EPR, and magnetic susceptibility studies.
