Crystal and molecular structure of tris-(1,10-phenanthroline)copper(II) perchlorate

Abstract

The crystal and molecular structures of the title compound have been determined from three-dimensional single-crystal X-ray diffraction data, collected by counter techniques. Crystals are monoclinic, space group C2/c, with Z= 8 in a unit cell of dimensions: a= 35·98(5), b= 15·97(3), c= 12·20(3)A, and β= 101·7(3)°. The structure was solved by Patterson and Fourier methods and refined by least-squares methods on alternate sets of atoms to R 0·133 for 2662 observed reflections. The monomeric complex cations exhibit a distorted octahedral configuration about copper(II), with equal distortions of the axial Cu–N bonds; mean Cu–N(eq) 2·04(1), mean Cu–N(ax) 2·33(1)A.
