Dichloridobis[(S)-2-hydroxy-propion-amide-κO,O']manganese(II)

Abstract

In the title compound, [MnCl(2)(C(3)H(7)NO(2))(2)], the Mn(II) ion is bound to two Cl atoms and to four O atoms from two lacta-mide mol-ecules which act as bidentate ligands, giving rise to a highly distorted octa-hedral coordination geometry. The axial positions are occupied by one Cl atom and one O (hydr-oxy) atom. The values of the cis bond angles at the Mn atom are in the range 72.33 (5)-100.17 (6)°. Of the two possible coordination modes (N,O- or O,O-bidentate) in metal complexes with lacta-mide or its derivatives described in the literature, the title compound exhibits the O,O-bidentate mode. In the crystal structure, monomeric manganese(II) complexes are linked by several N-H⋯Cl, O-H⋯Cl and O-H⋯O hydrogen bonds, generating a three-dimensional network.
