Hydrothermal syntheses, crystal structures, and properties of a novel class of 3,3′,4,4′-benzophenone-tetracarboxylate (BPTC) polymers

Three novel BPTC complexes, (H2BPTC)(4,4′-H 2bpy)H2O (1), [Cd2Cu(HBPTC)2(μ 2-4,4′-bpy)2(4,4′-bpy)2(H 2O)2]n (2), and [Co3(HBPTC) 2(μ2-4,4′-bpy)3(H2O) 4]n·2nH2O (3) (BPTC = 3,3′,4,4′-benzophenone-tetracarboxylate and bpy = bipyridine), were hydrothermally synthesized. Complex 1, which is obtained as a coproduct during the syntheses of complexes 2 and 3, features a 2-D layered strong hydrogen bonding network with 2-fold interpenetration. Complex 2 has an unusual 2-D double-layered motif, which is linked together by Cu atoms in a face-to-face manner. It exhibits nanosized channels filled by 4,4′-bpy ligands. Three six-coordinated Co atoms in 3 are interlinked by HBPTC ligands to form a 2-D grid structure, which is further sustained by rigid 4,4′-bpy ligands into a 3-D open framework similar to CdSO4 with the BPTC moieties situated in the tunnels. The thermal stabilities of complexes 1-3 were examined. The photoluminescence properties of complexes 1-2 and temperature-dependent magnetic susceptibility for 3 were also studied.
