Unusual Cd2(COO)4Cl2 building blocks for the construction of a dia or ths-type metal-organic framework
摘要:
A new three-dimensional (3D) metal-organic framework (MOF) [Cd(tpa)Cl](CH3)(4)N+ (1; tpa = 1, 4-terephthalic acid) with unusual Cd-2 (COO)(4)Cl-2 building block has been solvothermally synthesized and structurally characterized by the aid of single crystal X-ray diffraction, powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA) Elemental analysis (EA) and Infrared Spectroscopy (IR). The Cd-2(COO)(4)Cl-2 building block can be simplified as 4-connected or two 3-connected nods in different ways, correspondingly, the compound 1 exhibits 4-connected dia or 3-connected ths structural topology.
