Summary. Two novel compounds, [Co( phen) 3] 2V 4O 12· phen·22H 2O ( 1) and [Ni( phen) 3] 2 V 4O 12· phen·22H 2O ( 2), were prepared from KVO 3–1,10-phenanthroline ( phen)–Co(NO 3) 2, resp. NiCl 2–H 2O reaction systems. The compounds 1 and 2 are isomorphous and crystallize in triclinic system, space group P-1. Their crystal structures are formed by two types of layers parallel to 001: a cationic one consisting of [M II( phen) 3] 2+ ions and an anionic one containing the cyclic V 4O 12 4- anions. The solvate phenanthroline and crystal water molecules are located in the cationic and anionic layers, respectively. The IR spectra of 1 and 2 are consistent with the presence of the cyclic V 4O 12 4- anions in the complexes.
