The molybdate compound [(C10H10N2) (C10H9N2) (PMo12O40)] (C10H8N2) 2.7H2O was prepared by hydrothermal method and its crystal structure was determined. The crystal of the compound belongs to the monoclinic system with the space group P2 (1) / c. The unit cell parameters are a = 1.87700 (16) nm, b = 1.40329 (12) nm, c = (10) °, V = 6.7386 (10) nm3, Dc = 2.539 g / cm3, Z = 2, Mr = 2576.12, F (000) = 4960. The final deviation factor R1 = 0.0548, wR2 = 0.1342. The title compound molecule consists of one [PMo12O40] 3-, two protonated 4,4’-dipyridyl molecules with Keggin structure, two unprotonated 4,4’-bipyridine molecules and seven water molecules , There are abundant hydrogen bonds in the molecule.
