Crystal structures of thiocyanate polyaminecopper(II) complexes. Part I. Bis(ethylenediamine)copper(II) thiocyanate perchlorate

Abstract

Crystals of the title compound are orthorhombic, space group Pnam, with Z= 4 in a unit cell of dimensions a= 15·60(3), b= 7·62(2), and c= 10·82(3)Å. The structure was solved by Patterson and Fourier methods and refined by block-diagonal least-squares to R 0·083 for 1090 observed reflections measured photographically.

The copper ion is in a tetragonally distorted octahedral environment with four nitrogen atoms from ethylenediamine in an approximately square-planar configuration (Cu–N 2·02 Å) and the nitrogen atom from the thiocyanate group in the tetragonal positions (Cu–N 2·73 Å).
