Abstract
Three new Mn(II) complexes [Mn(HnicO)2(H2O)2] (1), [Mn2(HnicO)2SO4(H2O)2]n (2), and [NaMn(HnicO)3]n (3) (H2nicO = 2-hydroxynicotinic acid) have been synthesized and determined by X-ray diffraction. For complex 1, the mononuclear units with two bidentate HnicO- ions and two water molecules are assembled into a 3D architecture via hydrogen bonding and π-π interactions. For 2, Mn(II) ions are connected by μ3-HnicO- and μ2 - SO42 - bridging ligands, producing a 2D (6,3) coordination network. For 3, binuclear Na(I)-Mn(II) units with three carbonyl oxygen bridges are interlinked by carboxylate groups, resulting in a 3D 6-connected coordination network with distorted α-Po topology. The magnetic properties of 2 are discussed.
