摘      要：Solvothermal reactions of MnCl2with pyridylbenzoic acids gave three-dimensional metal-carboxylate frameworks(MCFs),named MCF-34,MCF-43,and MCF-44,based on one-dimensional Mn-carboxylate *** crystal structure,stability,porosity,and framework flexibility of the new compound MCF-44 were studied in detail and compared with its *** on their shapes and the bridging angles of the ligands,these compounds possess different network connectivities and *** the pyridylbenzote ligands and Mn(II)ions as,respectively,3-and 6-connected nodes,they resemble either the anatase(ant)or rutile(rtl)polymorph of ***-temperature single-crystal X-ray diffraction studies revealed large thermal expansion coefficients for these compounds,which are probably related to the relatively flexible edge-sharing polyhedral structure of their Mn-carboxylate ***,the new compound MCF-44,with its highly porous rtl structure exhibits the largest thermal expansion coefficienct among the coordination polymers reported so far.
