Complexes of 1-(4-Methoxyphenyl)-1,4-Dihydro-5H-Tetrazole-5-Thione and 1-(2-Methoxyphenyl)-1,4-Dihydro-5H-Tetrazole-5-Thione with Cadmium Chloride: Synthesis and Molecular and Crystal Structures

New complex compounds [Cd(μ-L1)2]n (I), [Cd(μ-L2)(μ-Cl)(μ-DMSO)]n (III), and [Cd2(μ-L2)(μ-Cl)3(μ-DMSO)DMSO/EtOH]n (IV) are synthesized by the reactions of 1-(4-methoxyphenyl)-1,4-dihydro-5H-tetrazole-5-thione (HL1) and 1-(2-methoxyphenyl)-1,4-dihydro-5H-tetrazole-5-thione (HL2) with cadmium chloride. The molecular and crystal structures of the complexes are determined by X-ray structure analysis (CIF files CCDC nos. 1993455 (I), 1869249 (III), and 1993497 (IV)). Complexes I, III, and IV have uniform polymeric structures. The О···Н, Cl···H, and C···S contacts are observed between 1D polymeric chains in the crystal cells of complexes I, III, and IV. Complexes III and IV contain DMSO molecules. Under other equivalent conditions, the reaction of HL1 or HL2 with cadmium chloride in ethanol affords complex I or II of different compositions. Complex II contains the chlorine atom as found by scanning electron microscopy, whereas no chlorine is observed in complex I according to the X-ray structure analysis data.
