Abstract：A two-dimensional Cd(II) supramolecular compound [Cd(H2O)]2[Cd(H2PO4)2(HPO4)4 (PO4)2(MoO2)12(OH)6]· (bbi)· (H2bbi)2· 4H2O][bbi=1,1′-(1,4-butanediyl)bis(imidazole)] has been hydrothermally synthesized and structurally characterized by single crystal X -ray diffraction analysis .C30 H72Cd3Mo12P8N12O68, triclinic, P 1, a=13.274(5)?, b=13.927(5)?, c=23.360(5)?,α=89.943(5)°,β=82.633(5)°,γ=77.037(5)°, Z=1, V=4172(2)?3 , Mr=3425.24, Dc =2.656 g/cm3 ,μ=2.760 mm-1 , F(000)=3135, S=1.026, R=0.0499, wR=0.1150.The crystal structure analysis indicates that the Cd 2+cat-ions exhibit the two kinds of coordinated environments .One type is that the Cd 2+cation is coordinated by six bridged oxygen atoms of MoO6 units from two [P4Mo6O28(OH)3]9-[P4Mo6] anions, forming a geometry dinuclear subunit .Another type is that two bridged oxygen atoms of PO 4 from two P4 Mo6 anions connect two Cd 2+to form a bimetallic [CdO(H2O)]2 subunit.The above subunits are interlinked alternately to generate one dimensional inor -ganic chain .The adjacent chains are linked by bbi ligands and the lattice water molecules through H -bonding in-teractions to form a two dimensional supramolecular network .Moreover , the photoluminescent and photocatalytic activity for the degradation of methylene blue under UV light of the title compound were investigated .CCDC:1458162.
