Four different types of polynuclear manganese(II) compounds with bhnq2− bridges were obtained from the reaction of Mn(CH3COO)2·4H2O with the flexible hinge-like ligand H2bhnq (H2bhnq = 2,2′-bi(3-hydroxy-1,4-naphthoquinone)) by controlling the reaction solvent: [Mn3(bhnq)3(H2O)2]·10.5H2O (1), [Mn2(bhnq)2(DMSO)4]·2DMSO·CHCl3 (2), {[Mn(bhnq)(H2O)2]·2H2O}n (3), and {[Mn(bhnq)(DMF)2]}n (4). All complexes are neutral with the same Mn/bhnq 1:1 formulation ratio. Compounds 1 and 2 are discrete systems, while compounds 3 and 4 are one-dimensional ones. All compounds were characterized by X-ray diffraction and show different coordination modes for the bhnq2− ligand.
Four different types of polynuclear manganese(II) compounds were obtained with the molecular hinge-like ligand bhnq2− by controlling the reaction solvent. There is a structural diversity among the Mn–bhnq complexes. The topology of the structures is easily controlled by the selection of the solvent.Figure optionsDownload as PowerPoint slide
