A novel thiocyanate-bridged one-dimensional chain complex: [Cu(NCS)2(Hambi)] (Hambi is 2-aminomethyl-1H-benzimidazole)
Abstract:Using 2-aminomethyl-1H-benzimidazole as the ligand, a new thiocyanate-bridged copper(II) complex, namely bis(2-aminomethyl-1H-benzimidazole-2N2,N3)dithiocyanatocopper(II),[Cu(NCS)2(C8H9N3)], has been synthesized and structurally characterized. The Cu atom is five-coordinated and exhibits a distorted square-pyramidal geometry. The thiocyanate ions (NCS−) act as either bridging or terminal ligands. The bridging NCS− ligands connect neighboring Cu atoms, constructing chains, while the terminal NCS− ligands form hydrogen bonds with amine H atoms, leading to a complicated network.
