Crystal and molecular structure of dichloro[(–)-α-isospartein]cobalt(II)

Abstract

The structure of the title complex has been determined by single-crystal X-ray analysis and refined by least-squares methods based on diffractometer data (1 366 counter intensities, R 0.033). The crystals are tetragonal, space group P4₃2₁2, with Z= 4, a= 8.034(1), and c= 25.295(2)Å. The cobalt(II) ion has a distorted tetrahedral co-ordination geometry with N–Co–N 89.0 and Cl–Co–Cl 109.0°. The observed distortions are compared with those reported for analogous (–)-spartein and (–)-β-isospartein metal complexes.
