摘要：

Two novel coordination polymers Zn(m-BDC)(4,4'-bipy) (.) C2H5OH 1 and Cd(m-BDC)(4,4'-bipy)(C2H5OH)-C-. 2 (m-BDC = 1,3-benzenedicarboxylic) have been synthesized under mild conditions and structurally characterized. Crystal data for 1: monoclinic P2/c, a = 10.058 (11) angstrom, b 11.401 (13) angstrom, c = 16.107 (2) angstrom, beta = 103.43(3)degrees, Z= 2. Crystal data for 2: monoclinic P2/c, a = 10.282 (15) angstrom, b = 11.716 (18) angstrom, c = 16.170 (2) angstrom, beta=103.21 (3)degrees, Z= 2. In the structures, the m-BDC ligands bridge the metal centers to form infinite I D chains, and the 4,4'-bipyr-idine ligands act as a pillar to link the adjacent chains to form an extended infinite 2D layer, which exhibit an interesting prismatic topology. The weak pi-pi stacking interactions extend the 2D layers into a 3D supermolecular framework. Additionally, these two compounds exhibit strong fluorescence at room temperature in the solid state.
