The title compound,Cd_(5)(BTC)_(4)(H_(2)O)_(8)·6H_(2)O(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 P2_(1)/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) nm~(3),Z=2,D_(c)=1.645 g/cm~(3),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 Cd_5(BTC)_4(H_2O)_8·6H_2O having “Z”-like shaped channels with the greatest dimensions about 2.6 nm viewed along the direction.
The title compound, Cd_ (5) (BTC) _ (4) (H_ (2) O) _ (8) · 6H_ (2) O (BTC = 1,3,5-benzenetricarboxylate) was synthesized under mild conditions, and its crystal structure was determined by the means of single crystal X-ray diffraction of the compound crystallizes in the monoclinic system and belongs to space group P2_ (1) / c with a = 1.022 6 (2) nm, b = 1.081 4 (2) (3), Z = 2 and D c = 1.645 g / cm 3, respectively, with the average value of nm, c = 2.987 6 (6) nm, β = 99.437 F = (0005) = 1 544, GOF = 1.082, R = 0.059 2, wR = 0.187 7. Its structure revealed that Cd1 and Cd2 centers are twice linked to BTC to form wave-like layers, and then the octahedral coordination geometries of Cd3 centers connect the condition above layers to construct the 3D framework of Cd_5 (BTC) _4 (H_2O) _8.6H_2O having “Z ” - like shaped channels with the greatest dimensions about 2.6 nm viewed along the direction.
