Dichloro zinc(II) complexes of 1-alkyl-2-(arylazo)imidazole, Zn(RaaiR′)Cl2 · H2O (RaaiR′ = p-R-C6H4-N = N-C3H2N-N(1)-R′: R = H, Me, Cl and R′ = Me, CH2CH3, CH2Ph) are characterized by elemental analysis, IR, UV-Vis and 1H NMR spectral data. The reaction of ZnCl2 and RaaiR′ (excess) in the presence of NH4CNS has synthesized Zn(RaaiR′)2(NCS)2. The single-crystal X-ray structure of dichloro-{1-methyl-2-(p-tolylazo)imidazole}zinc(II)-monohydrate (Zn(MeaaiMe)Cl2 · H2O) suggests that the complex is distorted trigonal bipyramidal (TBP) around Zn(II) with a trigonal plane constituted from Cl(1), Cl(2), N(imidazole) (N(1)). Molecular packing shows a 1D chain via a hydrogen bonded eight membered ring. The X-ray structure of di-thiocyanatobis-{1-methyl-2-(phenylazo)-imidazole}zinc(II) also shows a distorted TBP around Zn(II). The coordination sphere is ZnN3 type: where one of the ligands acts as a bidentate chelating agent and the second one coordinates via only the imidazole-N along with two N-centers from the NCS group.
