摘要

A new Cu(Ⅱ) coordination polymer,{[Cu3(oba)2(μ3-OH)2(H2O)2]·6H2O}n (H2oba =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) (A)3,Z =2,C28H36Cu3O20,Mr =883.09,Dc =1.913 g/em3,F(000) =782,p =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…π interactions 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.
