Crystal structures of thiocyanate polyamine copper(II) complexes. Part IV. Di-µ-thiocyanato-bis[di-(2-aminoethyl)amine]dicopper(II) diperchlorate

摘要: Crystals of the title compound are triclinic, space group P, with Z= 2 (i.e. 1 dimer) in a unit cell dimensions a= 11·81 (2), b= 7·48 c= (2)A, α= 70·9(3), β= 89·7(3), γ= 105·4(3)°. The structure was solved from diffractometer data by Patterson and Fourier methods refined block-diagonal least-squares to R 0·044 for 1564 observed reflections. co-ordination polyhedron copper(II) ion may be considered as tetragonally distorted octahedron, base formed amine (mean Cu–N 2·01 A) thiocyanate nitrogen (Cu–N 1·95 atoms, apical positions occupied sulphur (Cu–S 2·76 bridging long contact one perchlorate oxygen atom (Cu–O 2·90 A); if only five nearest contacts considered, is square pyramidal.
