catena-Poly[[manganese(III)-bis{μ-2-[(2-hydroxyethyl)iminomethyl]-6-methoxyphenolato-κ3O1,N:O2;κ3O2:N,O1}] iodide]

Abstract

In the title one-dimensional coordination polymer, {[Mn(C10H12NO3)2]I}n, the potentially tetradentate (O,O,O,N) 2-[(2-hydroxyethyl)iminomethyl]-6-methoxyphenol (H2L) ligands are mono-deprotonated (as HL−) and coordinated by the metal ions in a tridentate chelate-bridging fashion [2.0111112]. The MnIII atom possesses a distorted trans-MnO4N2 octahedral coordination environment. The bridging ligands lead to [010]-chain polymeric cations {[Mn(HL)2]+}n in the crystal. The charge-balancing iodide ions are disordered over two sites in a 0.690 (2):0.310 (2) ratio and a weak O—H...I hydrogen bond occurs. The crystal studied was found to be a racemic twin.
