N2 - A double-T-shaped ligand (H4BPTC) and bis(2-benzimidazole)alkanes as the spacers have been firstly used to direct the assembly of a 2D coordination polymer with wavy parquet network topology, [Zn(BPTC)0.5(H2C2EIm)(H2O)]n (1, C24H18ZnN4O5, Mr = 507.79, H4BPTC = biphenyl-3,3?,4,4?-tetracarboxylic acid, H2C2EIm = 2,2?-(1,2-ethanediyl)-bis(1H-benzimidazole), which was determined by single-crystal X-ray diffraction analysis. The crystal belongs to the monoclinic system, space group P21/n with a = 1.1844(5), b = 1.4019(5), c = 1.4026(5) nm, β = 108.359(5)°, V = 2.2104(15) nm3, Z = 4, Dc = 1.526 g/cm3, μ(MoKa) = 1.156 mm-1, F(000) = 1040, S = 1.038, the final R = 0.0427 and wR = 0.0793 for 3834 reflections with I > 2s(I). The compound units are linked through BPTC ligands into a wavilness parquet 2D layer and further connected into a 3D framework via p-p packing interactions between the adjacent H2C2EIm ligands and weak N-HO hydrogen bonding between uncoordinated carboxylate and the nitrogen atoms of H2C2EIm as well as the free water molecules.
