| Abstract: | The 2D coordination polymer {[Cu32( pa )24(μ2‐OH)8(μ3‐OH)8( bibp )8] · (CH3OH)3(H2O)5}∞ was prepared by the solvothermal reaction of Cu(NO3)2 · 3H2O with phthalic acid (H2 pa ) and 4, 4′‐bis(imidazol‐1‐yl)biphenyl ( bibp ). The CuII ions show five different kinds of coordination environments, which are all connected by the pa 2– ion into an interesting 1D carboxylate‐copper chain with rare icosacopper and tetracopper clusters. The 1D chain is further bridged by the bibp ligand to form a 2D layer, which could be viewed as an unprecedented (4, 4) lattice based on rectangular and butterfly‐shaped tetracopper clusters with the ratio of 2:6. The magnetic properties were studied, and the results show antiferromagnetic interaction in the complicated 1D chain. |
