Syntheses, structures and characterization of novel cobalt(II) mono- and bi-triazole complexes

Using the bi- and mono-triazole ligand, two novel cobalt(II) complexes [Co(L 1) 2(NCS) 2(H 2O) 2]·2H 2O ( 1) and [Co 3(L 2) 6(NCS) 4(H 2O) 2](NCS) 2·H 2O ( 2) (L 1=4-[3-(1,2,4-triazolyl)-1,2,4-triazole] and L 2=4-aminotriazole) have been synthesized. The crystal structures of 1 and 2 have been deter...

Summary:Using the bi- and mono-triazole ligand, two novel cobalt(II) complexes [Co(L 1) 2(NCS) 2(H 2O) 2]·2H 2O ( 1) and [Co 3(L 2) 6(NCS) 4(H 2O) 2](NCS) 2·H 2O ( 2) (L 1=4-[3-(1,2,4-triazolyl)-1,2,4-triazole] and L 2=4-aminotriazole) have been synthesized. The crystal structures of 1 and 2 have been determined by X-ray single-crystal diffraction. 1 has the mononuclear fundamental structure unit while 2 form the linear trinuclear structure unit. 1 and 2 were furthermore assembled into two-dimensional (2D) network and three-dimensional (3D) supramolecular complex via the intermolecular hydrogen-bonds, respectively. The complexes 1 and 2 also have been characterized by elemental analysis, FT-IR, UV/vis spectra.
