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 2O)] n ( 2), where H 2tbpc = 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 phenylsbnd 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.
