| Abstract: Two novel metal-organic frameworks {[Zn3(TCPB)2(4,4'-BPY)]·DMF·3H2O}n (1) with trinuclear zinc cluster units and {[Co1.5(TCPB)(DMF)(H2O)]·DMF}n (2) with trinuclear cobalt cluster SBUs, have been prepared under solvothermal conditions based on flexible 1,3,5-tri(4-carboxyphenoxy) benzene ligand (H3TCPB) with the help of ancillary bridging N-donor pyridyl linker 4,4'-bipyridine (4,4'-BPY), and characterized by single crystal X-ray diffraction, IR spectra, elemental analyses, thermogravimetric analyses (TGA) and powder X-ray diffraction (PXRD). The single crystal X-ray diffraction analysis reveals that complex 1 crystallizes in triclinic space group P1 and exhibits three-dimensional (3D) (3,8)-connected network with Schläfli symbol of {43}2·{46·618·84}·{6}, complex 2 also belongs to the triclinic system with space group of P1 and shows two-dimensional (2D) (3,6)-connected net-like layered framework with Schläfli symbol of {43}4·{46·618·84}. In addition, the study of the solid state photoluminescent property of complex 1 indicates that it emits light blue fluorescence arising from TCPB3- and 4, 4'-BPY ligands at room temperature, while complex 2 is non-emissive under similar conditions. |
