Abstract
A 1:1 complex of copper(II) azide with 3-picoline has been synthesized and shown to be polymeric by X-ray crystallography. The compound crystallizes in space group C2/c, with a = 23.120(9), b = 13.751(4), c = 6.663(2) Å, β = 100.43(2)°, and Z = 8. The structure has been refined to R F= 0.063 for 979 observed MoKα diffractometer data. Two azido ligands lying on a crystallographic diad bridge a pair of copper atoms to form a planar Cu 2N 2 ring. The rings are linked alternately by pairs of a third type of azido ligands which asymmetrically bridge copper atoms related by the c glide, giving rise to a composite column structure. The coordination geometry about the copper atom is distorted trigonal bipyramidal, with the 3-picoline ligand occupying one of the axial positions. Infrared and electronic spectral data are also presented and discussed.
