Two 2-Fold Interpenetrated Frameworks Showing Different Topologies Based on the Isomerous Benzenedicarboxylate Mixed with a Flexible N,N‘-Type Ligand

This paper presents two 2-fold parallel interpenetrated polymers, namely ZnCo(bpp)(m-BDC)2 (1) and Co(bpp)(p-BDC)(2), based on isomerous 1,3-benzenedicarboxylate (m-BDC) and 1,4-benzenedicarboxylate (p-BDC). Compounds 1 and 2 have been hydrothermally synthesized and characterized by single-crystal X...

Description
Summary:This paper presents two 2-fold parallel interpenetrated polymers, namely ZnCo(bpp)(m-BDC)2 (1) and Co(bpp)(p-BDC)(2), based on isomerous 1,3-benzenedicarboxylate (m-BDC) and 1,4-benzenedicarboxylate (p-BDC). Compounds 1 and 2 have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, IR, ICP, TGA, DSC, and element analysis. 1 crystallizes in the triclinic space group P1̄ and affords a three-dimensional (3D) six-connected α-Po network, whereas 2 crystallizes in the orthorhombic space group Pbca and gives an usual 2D four-connected 44 grid. These interpenetrated topologies should be attributed to the high functionality and adaptability of the 1,3-bis(4-pyridyl)propane (bpp) ligand.
