Abstract
[MCl(2)L(4)] complexes (M=Co or Ni;L=3-hydroxypyridine) were prepared by the reaction of stoichiometric amounts of 3-hydroxypyridine and MCl (2) in EtOH solution. The complexes were chlorinated by passing Cl-2 g as through EtOH solutions containing the metal(II) chloride and 3-hydr oxypyridine to yield [CoCl2(LCl)(2)].2H(2)O and [NiCl2(LCl)(4)].4H(2)O , respectively. Structural assignments have been inferred from element al and spectral analyses. Magnetic properties of the complexes are ass igned and the electronic transitions are discussed.
