Abstrakt: [MCl2L4] complexes (M = Co or Ni; L = 3-hydroxypyridine) were prepared by the reaction of stoichiometric amounts of 3-hydroxypyridine and MCl2 in EtOH solution. The complexes were chlorinated by passing Cl2 gas through EtOH solutions containing the metal(II) chloride and 3-hydroxypyridine to yield [CoCl2(LCl)2]·2H2O and [NiCl2(LCl)4]·4H2O, respectively. Structural assignments have been inferred from elemental and spectral analyses. Magnetic properties of the complexes are assigned and the electronic transitions are discussed.
