  Synthesis and structure of new mononuclear octahedral cobalt(III) dioximates derived from isonicotinic hydrazide

  摘要：

  New organic ligand L (1) resulting from isonicotinic hydrazide and 2,4-pentanedione has been prepared and investigated by physicochemical methods, including elemental analysis, H-1 and C-13 NMR, IR spectroscopy and X-ray studies.The X-ray investigation revealed that the condensation of 2,4-pentanedione with isonicotinic hydrazide is accompanied by the formation of a five-membered ring including three carbon atoms of 2,4-pentanedione and two nitrogen atoms of the isonicotinic hydrazide fragment.The reaction between [Co(DfgH)(2)Br(H2O)] (DfgH(2) = diphenylglyoxime) and L resulted in the formation of the mononuclear octahedral complex [Co(DfgH)(2)BrL] (2) with the substitution of the water molecule in the apical position by the ligand L. The reaction starting from (Co(DmgH)(2)Cl(H2O)] (DmgH = dimethylglyoxime) and L resulted in the mononuclear octahedral Co(III) complex with the composition [Co(DmgH)(2)CIL'] (3), where L' unexpectedly represents a dehydrated derivative of L. The two coordination compounds are characterized by X-ray diffraction method. The IR, H-1 NMR spectral studies of new compounds are also reported. (C) 2014 Elsevier B.V. All rights reserved.
