One new polyoxometalate(POM)-based inorganic–organic hybrid [CdII3(HPO4)(Hbpp)(H2O)2]{CdII[P4-Mo6O28H3.5(OH)3]2}(H4tpb) 7H2O(1)(bpp = 1,3-bis-(4-pyridyl)propane, tpb = 1,2,4,5-tetra(4-pyridyl)-benzene) constructed from reduced molybdophosphate [P4Mo6O28H3.5(OH)3]5.5(P4Mo6), trinuclear CdII-phosphate-Hbpp fragment and protonated tpb has been hydrothermally synthesized and structurally characterized by IR, elemental analyses and single crystal X-ray diffraction. The complex1 crystallizes in the monoclinic system with the space group P21/c and cell parameters of a = 15.672(12), b = 23.839(19), c = 27.654(2), b = 115.850(10)8, V = 9297.9(12) 3, Z = 4,R1= 0.0534 and wR2= 0.1135. In complex 1, the P4Mo6units are bridged by CdIIions to form the classic sandwich-type [Cd(P4Mo6)2] dimers, which are further connected into a two dimensional network via the trinuclear CdIIsubunits. The tpb is synthesized in situ from the bpp ligands and connects the adjacent 2D layers into a 3D supramolecular framework through hydrogen bonding interactions. The electrochemical and fluorescent properties of complex 1 have been investigated.
