| Abstract: | Three new zinc(II)/cobalt(II) coordination complexes Zn(HBTB)(L)0.5] ( 1 ), Zn(HCPPA)(L)] ( 2 ), and Co(HCPPA)(L)] · 2H2O ( 3 ) H3BTB = 1,3,5-tri(4-carboxylphenyl)benzene, H3CPPA = 5-(4-carboxyl-phenoxy)-isophthalic acid, L = N1,N4-bis(3-pyridyl)naphthaldiamide] were solvothermally synthesized. The structural characterization reveals that complex 1 represents a 3D coordination framework with a binodal 3,4-connected {4.102}2{4.105}2 topology constructed from the 2D Zn(HBTB)]n polymeric double-layers and the bidentate L ligands. Complex 2 is a 1D metal-organic chain derived from the dinuclear Zn2(HCPPA)2] loops and Zn2(L)2] loops. Complex 3 possesses a binodal 3,5-connected {42.6}{43.6.84.102} topological 2D layered architecture based on the Co2(HCPPA)2] ribbon chains and the bidentate L ligands. For 2 and 3 , their adjacent chains or layers are respectively stacked into 3D supramolecular architectures via the hydrogen bonds. Moreover, the fluorescent and fluorescent sensing activities towards small solvent molecules of coordination complexes 1 and 2 , the photocatalyitc properties of 1 – 3 towards organic dyes were studied. |
