The MoVI atom in the title co-crystal, [Mo(C14H12N2O4)O2(H2O)]·0.5C10H8N2, is O,N,O′-chelated by the deprotonated Schiff base and coordinated by the oxide and water O atoms in an octahedral geometry. The five-membered chelate ring is planar (r.m.s. deviation = 0.019 Å), but the six-membered chelate ring is puckered (r.m.s. deviation = 0.108 Å). Two mononuclear molecules are linked across a center of inversion by an O—Hwater...O hydrogen bond; adjacent dinuclear units are linked by an water–4,4′-bipyridine O—H...N hydrogen bond, generating a linear chain structure. The 4,4′-bipyridine molecule is disordered over two positions in a 1:1 ratio.
