摘要
Hydrothermal reaction of Cu(NO3)2·3 H2O and 4-(4-carboxyphenoxy)isophthalic acid(H3cpia)results in a two-dimensional coordination polymer based on paddle-wheel-like dinuclear clusters,namely[C60H54Cu4O39]n(1).Complex 1 is of triclinic system,space group P1 with a=10.7318(18),b=12.267(2),c=14.528(2)?,α=113.560(2)o,β=96.156(3)o,γ=103.552(3)o,V=1660.5(5)?3,Z=1,S=1.057,F(000)=842,R=0.0517 and wR=0.1426(I>2σ(I)).In this structure,tricarboxylate liagnds are partial deprotonation and potenial proton carriers.Strong antiferromagnetic interaction between CuⅡions exists within the Cu2 cluster and complex 1 exhibits relatively high proton conductivity(σ>1.23×10-5 S×cm-1)at 76%relative humidity(RH).
