A two-dimensional manganese(II) complex: poly[bis(μ2-4,4′-bipyridyl)tetrakis(μ2-3,5-dinitrobenzoato)dimanganese(II)]

Abstract

The Mn atom in the title compound, [Mn2(C7H3N2O6)4(C10H8N2)2]n, is six-coordinated by two N atoms and four O atoms, forming a distorted octahedral geometry. The Mn—O bond lengths are in the range 2.1281 (13)–2.2011 (12) Å and the Mn—N bond lengths are 2.269 (2) and 2.278 (2) Å. Mn(II) atoms are double-bridged along the a axis by two pairs of bi-monodentate carboxyl groups, forming a double-stranded chain, while the bidentate 4,4′-bipyridine ligand bridges the Mn atom along the b axis. This results in a two-dimensional structure constructed of oblong grids with the sides of length 11.634 and 5.075 Å
