Abstract

An X-ray diffraction analysis of [Co(HEdda)En(CN)]HgCl3 crystals (a = 6.664(4), b = 16.613(13), c = 16.684(7) å, space group P212121, Z = 4) showed that the crystals contain distorted tetrahedra HgCl4 linked by one of their vertices into infinite chains [HgCl3] n-n . In isolated complex cations, three donor atoms of the HO2CCH2NHCH2CH2NHCH2CO -2 (HEdda) ion occupy a face of the coordination octahedron around the cobalt atom; the opposite face is occupied by the cyanide ion and the nitrogen atoms of the ethylenediamine (En) molecule; the latter are in trans positions relative to the terminal donor atoms of the HEdda ligand.
