【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=1.022 6（2） nm, b=1.081 4（2） nm,c=2.987 6（6） nm,β=99.437（3） °,V=3.259 1（11） nm³,Z=2,D_c=1.645 g/cm³,M_r=807.23,μ=1.691 mm^-1,F（000）=1 544,GOF=1.082,R=0.059 2,wR=0.187 7. 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 direction.更多还原
