✦ Synopsis

MC12L4] complexes (M = Co or Ni; L = 3-hydroxypyridine) were prepared by the reaction of stoichiometric amounts of 3-hydroxypyridine and MC12 in EtOH solution. The complexes were chlorinated by passing CI/gas through EtOH solutions containing the metal(II) chloride and 3-hydroxypyridine to yield [CoCI2(LC1)z]-2H20 and [NiClz(LC1)4]'4H20, respectively. Structural assignments have been inferred from elemental and spectral analyses. Magnetic properties of the complexes are assigned and the electronic transitions are discussed.

In the title complex, [CoCl 2 (C 5 H 5 NO) 4 ], the Co atom is in an elongated octahedral environment, de®ned by two Cl À ions and four N atoms of 3-hydroxypyridine ligands. The Co atom lies on a special position with crystallographic twofold rotation symmetry. Individual molecules are linked by int
