摘要：

The complexes obtained by crystallisation from an aqueous solution of molybdate and citric acid (H4cit) at pH 4-8 have Mo:cit ratio 1:1. The new complexes have been characterised by a variety of methods in the solid state and in solution. On this basis two dimeric species, [(MoO2)2O(citH)2]4- and [(MoO2)2O(cit)2]6-, and a monomeric species [MoO3(cit)OH2]4- are proposed.
