Metal-organic coordination architectures of tetrazole heterocycle ligands bearing acetate groups: Synthesis, characterization and magnetic properties

Two new coordination complexes with tetrazole heterocycle ligands bearing acetate groups, [Co(L)(2)](n) (1) and [Co-3(L)(4)(N-3)(2)center dot 2MeOH](n) (2) (L=tetrazole-1-acetate) have been synthesized and structurally characterized. Single crystal structure analysis shows that the cobalt-complex 1 has the 3D 3,6-connected (4(2).6)(2)(4(4).6(2).8(8).10)-ant topology. By introducing azide in this system, complex 2 forms the 2D network containing the [Co-3] units. And the magnetic properties of 1 and 2 have been studied. (C) 2015 Elsevier Inc. All rights reserved.
