Five-co-ordinate cadmium(II) in [bis(2-dimethylaminoethyl)methylamine]di-isothiocyanatocadmium(II)

Abstract

The crystal structure of the title compound has been determined from three dimensional X-ray data. Crystals are monoclinic, space group P2₁/c, with Z= 4 in a unit cell of dimensions: a= 13.75(2), b= 7.68(1), c= 16.23(3)Å, β= 97.0(3)°. The structure was solved by the heavy-atom method and refined by least-squares techniques to R 0.033 for 2 370 observed reflections measured by diffractometer. The molecular geometry is close to square-pyramidal with the basal positions occupied by the amine [Cu–N(prim) 2.34, Cu–N(sec) 2.37 Å] and thiocyanate nitrogen (Cd–N 2.21 Å) atoms; the apical position is filled by the nitrogen of the second thiocyanate group (Cu–N 2.18 Å).
