Complexes 7-12, 16, 22 and 23 are dimeric molybdatesor dimeric tungstates, the central metal with citrate or malate in a molar ratio of 1:1. Theanions of these complexes have two metal atoms and two ligands. Each ligand acts as atridentate fashion via theirα-alkoxy,α-carboxy andβ-carboxy groups coordinated to eachmetal atom. Complex 13 is a monomeric molybdate. The citrate ligand coordinates tomolybdenum with itsα-alkoxy,α-carboxy andβ-carboxy groups in a tridentate mode.
