Hydrothermal synthesis, crystal structures and TGA of two metal-organic frameworks from 2'-(1H-tetrazol-5-yl)-[1,1'-biphenyl]-4-carboxylic acid

Abstract Two novel coordination compounds [Zn(tbpc)] n ( 1 ) and [Cd(tpbc)(H 2 O)] n ( 2 ), where H 2 tbpc = 2′-(1H-tetrazol-5-yl)-[1,1′-biphenyl]-4-carboxylic acid, have been synthesized through hydrothermal method. In 1 and 2 , the tbpc adopts different quadridentate bridging modes to connect metal (Zn/Cd) centers to form distinct two-dimensional layers, which are stacked in different sequence. The C phenyl H⋯π interactions play a central role in packing 2D layers to form 3D structure. The preliminary investigation on the thermal stability of the complexes is presented.
