Abstract
A hybrid compound,NH4[Cu31(C10H8N2)3Mo8O26](1),has been hydrothermally synthe-sized and structurally characterized by elemental analysis and single crystal X-ray analysis.The com-pound crystallizes in triclinic,space group P (1) with a=1.08763(9)nm,b=1.12674(10)nm,c=1.13067(10)nm,α=68.4820(10)°,β=83.523(2)°,γ=64.4180(10)°,V=1.16095(2)nm3,Z=1,De=2.661 g/cm3,Mr=1860.73,μ(MoKα)=35.22 cm-1,F(000)=888,R=0.0478,wR=0.099.The structure is composed of discrete polyoxoanion β-[Mo8O26]4- and infinite[Cu1(C10H8N2)]chains with two crystallographically independent copper atoms.Each of two copper atoms exhibits similar { CuN2 } coordination mode,and is linked by 4,4'-bipyridine molecule to one-dimensional[Cu(C10H8N2)]+chain along the a axis.There exists hydrogen bonds andπ…πinterac-tions in the molecular structure.Moreover,the thermal stability and photoluminescence property are studied as well.
