Hydrothermal syntheses of two novel coordination polymers based on tetranuclear metal cluster constructed by 1,3,5-Tris(2H-tetrazol-5-yl)benzene ligand

Two new coordination polymers, namely [Zn-3(BTT)(mu(3)-OH)(3)] (1), and [Mn-3(BTT)(mu(3)-OH)(3)] (2), where H3BTT=1,3,5-Tris(2H-tetrazol-5-yl)benzene, have been synthesized under hydrothermal conditions and characterized by single crystal X-ray diffraction. The structure of compound I can be described as tetranuclear zinc cluster linked with zinc (Zn2(II)) atoms to form a 2D layer, and the adjacent parallel layers bridged by the rigid H3BTT ligand to show 3D network. Taking Mn ions in replace of Zn ions, a new compound 2 is successfully obtained which is isostructural with 1. In addition, photoluminescent property for 1, magnetic properties for 2 and thermogravimetric analyses for 1 and 2 are investigated in detail. (C) 2010 Elsevier B.V. All rights reserved.
