Abstract

The title complex [Co2(bte)3(NCS)4(H2O)2] n (bte = 1,2-bis(triazol-1-yl)ethane) has been prepared. Single-crystal X-ray analysis reveals that the complex crystallizes in space group P ī with a = 7.7962(2), b = 8.3407(4), c = 14.7735(5) Å, α = 86.835(2), β = 76.2031(9), γ = 80.583(3)°. The crystal consists of two discrete complexes, [Co(bte)(NCS)2(H2O)2] and [Co(bte)2(NCS)2]. The structure of [Co(bte)(NCS)2(H2O)2] consists of neutral chain containing Co(II) bridged by bte molecules. The six-co-ordination of Co2+ is achieved by means of two trans NCS− ions and water molecules. The structure of [Co(bte)2(NCS)2] demonstrates a one-dimensional neutral chain through bte-bridge, in which the Co(II) atom is in a distorted octahedral environment formed by four nitrogen atoms of the triazoles and two nitrogen atoms from two trans thiocyanato liagnds.
