Abstract

A series of complexes of the types ML2X2 and ML4X2 have been examined both in the solid state and in solution in organic solvents; M= Co(II), Ni(II) or Zn(II); L= pyridine, monosubstituted pyridine, quinoline or isoquinoline; X = halide or pseudohalide ion. Solid state structures have been assigned on the basis of magnetic moments and electronic spectra and (in the case of zinc complexes) X-ray powder crystallography and IR spectra. the bisamine complexes, ML2X2, were found, for the most part, to have either 4-coordinate (tetrahedral) or 6-coordinate (bridged octahedral) structures; a few of the Ni(II) complexes are planar. Many of the ML2X2 complexes dissolve in chloroform, with configurational rearrangement to the tetrahedral form where necessary, and also exist in equilibrium, in the presence of excess of the appropriate amine, with the corresponding mononuclear octahedral complex.
