Graphycal Abstract:
Two new compounds – a mononuclear nickel(II) compound with di-paratolylglyoxime (DpatH2) - [Ni(DpatH2)3]SO4∙1,4-H2bdc∙2.5DMF∙H2O (1) and a binuclear manganese(II) compound with dianilineglyoxime (DAnH2) - [Mn2(DAnH2)2(1,3-bdc)2(DMSO)4] (2) (1,4- and 1,3-bdc are 1,4- and 1,3-benzenedicarboxylic acids, respectively) have been obtained. The IR spectra of the complexes were studied and molecular and crystal structures of the compounds were determined by single crystal X-ray diffraction method. Compound 1 is ionic and contains a complex cation in which three neutral DpatH2 ligands are coordinated to the nickel atom. Complex 2 is a molecular binuclear complex in which, in addition to the two neutral ligands DAnH2 and four DMSO, two 1,3-benzenedicarboxylic anions are coordinated to the metal atoms in a bridging manner.
