Construction and photoluminescence properties of two novel zinc(II) and cadmium(II) benzyl-tetrazole coordination polymers

Two new d(10) coordination polymers. Zn(Beta)(2) (1) and Cd-2(Beta)(3)Cl(H2O) (2) (Hbeta = 5-benzyl-tetrazole) have been synthesized by the in situ [3 + 2] cycloaddition reaction of 5-benzylacetonitrile, sodium azide and MCl2 [M = Zn (1); M = Cd (2)] under hydrothermal condition, Complex 1 is a coordination polymer comprised of numerous mildly undulated two-dimensional (2D) layers with a (4,4) topological network; while complex 2 is a 3D coordination framework constructed from the interconnection of various helical chains through cadmium-chlorine bridges. Furthermore, the luminescence properties of two complexes have been investigated. (C) 2009 Elsevier B.V. All rights reserved.
