Mn and Cu-Na coordination compounds containing the tetrazole-5-acetato anion (tza) ligands

Two novel coordination compounds [Mn(tza) center dot (H2O)(2)](n) (1) and [CuNa2(tza)(2)center dot (H2O)(4)]n (2) (tza = tetrazole-5-acetato) were synthesized by reaction of tetrazole-5-ethyl acetate with Mn(ClO4)(2) center dot 6H(2)O and CuCl2 center dot 2H(2)O in sodium hydroxide solution, respectively. Compound 1 has a one-dimensional (1D) polymeric chain that are bridged by tza linker, while compound 2 has two crystallographically independent metal centers (Cu and Na), that are bridged by tza into a 2D layer structure. The magnetic susceptibility study of I demonstrates the presence ofantiferromagnetic interaction between two adjacent Mn(II) ions. (c) 2008 Elsevier B.V. All rights reserved.
