Crystal structures of thiocyanate polyamine copper(II) complexes. Part II. Bis-(1,3-diaminopropane)isothiocyanatocopper(II) perchlorate

Abstract

Crystals of the title compound are hexagonal, space group P6₃, with Z= 6 in a unit cell of dimensions a=b= 13·75(2), c= 14·55(2)Å. The structure was solved from diffractometer data by Patterson and Fourier methods and refined by full-matrix least-squares techniques to R 0·064 for 1206 observed reflections. The co-ordination polyhedron of the copper(II) ion is a distorted trigonal bipyramid, the co-ordination sites being occupied by amino and thiocyanate nitrogen atoms, with Cu–N(axl) 2·01, Cu–N(eq) 2·10, and Cu–N(NCS) 2·11 Å.
