Abstract: Single crystals of dianilineglyoxime (DAnH2) in the form of hydrate salts [DAnH3](ClO4) ∙ H2O (I) and [DAnH3](ClO4) ∙ 1.25H2O (II) are obtained. Three binuclear zinc(II) and manganese(II) compounds with dianilineglyoxime and 1,3-benzenedicarboxylic acid (1,3-Н2Bdc) are synthesized: [Zn2(DAnH2)2(1,3-Bdc)2(DMF)4] ∙ 2DMF ∙ MeOH · 1.5H2O (III), [Mn2(DAnH2)2(1,3-Bdc)2(DMF)4] ∙ 2DMF (IV), and {[Mn2(DAnH2)2(1,3-Bdc)2(DMF)2(CH3OH)2][Mn2(DAnH2)2(1,3-Bdc)2(DMF)4] ∙ 2CH3OH} (V). The compositions and structures of compounds I–V are confirmed by IR spectroscopy and X-ray diffraction analysis (CIF files CCDC nos. 1906360 (I), 1906362 (II), 1906361 (III), 1906363 (IV), and 1906364 (V)). The X-ray diffraction data show that DAnH2 coordinates to the metal ions via the bidentate chelate mode, whereas (1,3-Вdc)2– coordinates to the metal ions via the bidentate bridging mode to form binuclear structures. As the most part of α-dioximes, one neutral DAnH2 coordinates to each metal atom by two nitrogen atoms, whereas two (1,3-Вdc)2– anions coordinate to the metal atom by one oxygen atom each. The coordination polyhedra of the metals in compounds III–V are built up by the oxygen atoms of DMF and CH3OH. |
