A series of new addition compounds of bis(2-hydroxyaryloximato) nickel(II), [Ni(ox)2], with an α-diimine (enR), under the general formula [Ni(ox)2enR], were synthesized and characterized. The IR and electronic excitation spectra indicate that the bidentate coordination mode of the ligands consists with the chromophore NiN4O2. The octahedral environment around nickel(II) was confirmed by an X-ray structure analysis of [1,10-phenanthroline-bis(2-hydroxy-benzaldoximato)nickel(II)], [Ni(saox)2phen]·H2O. The equatorial plane, which encompasses the nickel atom, is formed by four nitrogen atoms, two coming from the phenanthroline molecule and two from the two molecules of the 2-hydroxybenzaldoxime (salicylaldoxime). In the apical positions lie the two deprotonated phenolic oxygen atoms of the two salicylaldoxime ligands. The thermal stability and decomposition mode were studied in nitrogen using the technique of thermogravimetry (TG/DTG). Mass spectrometry was also used, and possible fragmentation patterns are given and discussed. Elsevier Science Ltd.
