Synthesis and structure of a one-dimensional cobalt(ii) coordination polymer with 1,3-bis(1,2,4-triazol-1-yl)propane

Abstract

A novel 1D-coordination polymeric Co(II) complex [Co(btp)2(NCS)2]n [1, btp = 1,3-bis(1,2,4-triazol-1-yl)propane] was synthesized and characterized. The coordination geometry of the cobalt ions is distorted octahedral, with the equatorial plane formed by the four nitrogen atoms of the four triazole groups and the axial sites occupied by two terminal trans thiocyanato ligands. The Co(II) ions are linked by the btp ligands, building up coordination polymers of infinite 1D-neutral chains.
