Abstract

Abstract: The title compound, Cd₅(BTC)₄(H₂O)₈·6H₂O(BTC=1,3,5-benzenetricarboxylate) was synthesized under mild conditions, and its crystal structure was determined by means of single crystal X-ray diffraction. The compound crystallizes in the monoclinic system and belongs to space group P2₁/c with a=1.0226(2) nm, b=1.0814(2) nm, c=2.9876(6) nm, β=99.437(3) °, V=3.2591(11) nm³, Z=2, D_c=1.645 g/cm³, M_r=807.23, μ=1.691 mm^-1, F(000)=1544, GOF=1.082, R=0.0592, wR=0.1877. Its structure revealed that Cd1 and Cd2 centers are firstly linked with BTC to form wave-like layers, and then the octahedral coordination geometries of Cd3 centers connect the neighboring above layers to construct the 3D framework of Cd₅(BTC)₄(H₂O)₈·6H₂O having “Z”-like shaped channels with the greatest dimensions about 2.6 nm viewed along the [100] direction.
