Syntheses, crystal structures, and properties of two new ion-pair compounds based upon bis(1,2,5-thiadiazole-3,4-dithiolate)nickelate anion and substituted benzyltriphenylphosphium cations

摘要

Two new ion-pair compounds based on [Ni(tdas)2]~(2-) (tdas = 1,2,5-thiadiazole-3,4-dithiolate) anion with substituted benzyl triphenylphosphium cation, [2ClBzTPP]~2[Ni(tdas)_2](1) and [4ClBzTPP]_2[Ni(tdas)_2](2), have been prepared and characterized by UV, IR, ESI-MS, molar conductivity, and single-crystal X-ray diffraction. Single-crystal X-ray diffraction analyses indicate that 1 crystallizes in the triclinic space group P-1, while 2 crystallizes in the monoclinic space group P2_1. Some intramolecular contacts such as C-H?Cl, C-H?S, C-H?N or S?Cl weak interactions observed in 1 and 2 consolidate the crystal packing and generate a 3D network structure.
