Cd(II)–NCS/NCO complexes of 1-alkyl-2-(arylazo)imidazole: Single crystal X-ray structure of [Cd(HaaiMe)2(SCN)2]

The reaction of Cd(OAc)2 · 4H2O and 1-alkyl-2-(arylazo)imidazole [RaaiR′ where R = H (a), Me (b); R′ = Me (1/3/5), Et (2/4/6)] and NH4NCS/NaNCO in methanol in 1:2:2 mole ratio has afforded [Cd(RaaiR′)2(NCS)2] (3, 4) and [Cd(RaaiR′)2(NCO)2] (5, 6) complexes. The complexes are characterized by different physicochemical methods and in one case, the structure was confirmed by single crystal X-ray diffraction study for title compounds.
