A Novel 3D Metal Coordination Polymer Based on Tetranuclear Zinc Cluster Building Blocks: Syntheses, Structures and Photoluminescent Property

A novel 3D metal coordination polymer (MCP), {[Zn-2(A mu(3)-OH)(btc)(bmip)]center dot H2O}(n) (1), where H(3)btc = 1,3,5-benzenetricarboxylate acid, bmip = 1,3-bis(2-methylimidazolyl)propane, was synthesized under hydrothermal conditions and characterized by single crystal X-ray diffraction, powder XRD, FT-IR, TGA and elemental analysis techniques. Single crystal X-ray analysis revealed that MCP 1 features a 3D framework based on tetranuclear Zn(II) Clusters where the four zinc ions are coplanar, and shows an unusual binodal (3,10)-connected topology. Furthermore, the photoluminescent property of MCP 1 was investigated at room temperature. [GRAPHICS] .
