摘要
A new Cu(Ⅱ)coordination polymer,{[Cu3(oba)2(μ^3-OH)2(H2O)2].6H2O}n(H2 oba=4,4’-oxydibenzoic acid),was synthesized by the solvothermal route and characterized by IR,TGA and XRD.The complex crystallizes in the monoclinic system,space group P21/c with a=5.957(6),b=29.746(3),c=9.351(7)A,β=125.709(4)°,V=1345.4(2)A3,Z=2,C28H36Cu3O20,Mr=883.09,Dc=1.913 g/cm^3,F(000)=782,μ=2.427 mm-1,R=0.0780 and wR=0.1688 for 3120 observed reflections with I>2σ(I).The complex forms a 3D framework based on rare infinite rod-shaped secondary building units(SBUs),and C-H…πinteractions play an important role in stabilizing the 3D supramolecular architecture.It shows excellent catalytic activities for the degradation of safranin O(SO)and methylene blue(MB)dyes in aqueous solution under UV light irradiation.Furthermore,the apparent rate constants have also been investigated.
