Linear trinuclear [Mn3(COO)4] clusters as SBUs for the construction of a new ant-type manganese(II) coordination polymer: Synthesis, structure and magnetic properties.

Abstract: A new Mn(II) compound, namely [Mn3(OABDC)2(H2O)4]n (1 H3OABDC=5-oxyacetateisophthalic acid), has been synthesized through combination of H3OABDC and MnCl2 under solvothermal conditions. A single crystal X-ray analysis reveals that 1 is a complicated three-dimensional (3D) framework based on trinuclear [Mn3(COO)4] subunits, which can be simplified into a (3, 6)-connected ant network. Variable temperature magnetic investigation reveals that this compound exhibits antiferromagnetic behavior. [Copyright &y& Elsevier]
