Organometallic oxovanadium (IV) complexes having potent spermicidal activity, particularly those having at least one bidentate ligand. Preferred compounds are stable oxovanadium (IV) complexes having, as ancillary ligands linked via nitrogen or oxygen-metal bonds, bis and/or mono-1,10-phenanthroline; 2,2'-bipyridyl; or 2-hydroxyacetophenone. |
