Abstract

Complexes [Сu(NCS)2L2]n, where L is 1-tert-butyl-1,2,4-triazole, 1-ethyltetrazole and 2-tert-butyltetrazole, were obtained by the interaction of metallic copper, ammonium thiocyanate and N-alkylazoles (L). According to single crystal X-ray analysis, the synthesised complexes are 1D coordination polymers. In them, azoles act as monodentate ligands, coordinated at the N4 atom of the heterocycle. The thiocyanate anions exhibit bridging N, S-coordination to bind copper(II) cations in coordination chains. The copper(II) cations have essentially elongated octahedral environment, with two N4 atoms of azole ligands and two thiocyanate nitrogen atoms in the equatorial positions, and two thiocyanate sulfur atoms in the axial sites.
