Tetraaquabis(4-methoxyphenylacetato-O')magnesium(II) dihydrate and catena-poly[[(diaqua)manganese(II)]-bis(μ2-4-methoxyphenylacetato-O,O')]: A monomeric and a two-dimensional coordination polymer based on 4-methoxyphenylacetic acid

Abstract

The synthesis and characterization of tetraaquabis(4-methoxyphenylacetato-O')magnesium(II) dihydrate (1) and catena-poly[[(diaqua)manganese(II)]bis(μ₂-4-methoxyphenylacetato-O,O')] (2) based on 4-methoxyphenylacetic acid (4-mpaH) ligand is reported. In 1, the unique 4-mpa functions as a monodentate ligand for Mg(II) situated on an inversion centre, resulting in a monomeric Mg(II) complex. The Mn(II) in 2 is also located on an inversion centre and the μ₂-bridging bidentate coordination mode of the unique 4-mpa ligand results in the formation of a two-dimensional manganese coordination polymer.
