“…Their molar conductivities are in a range corresponding to a non-electrolytic nature. These results agreed with measurements of the conductivity carried out with their homologous thiosemicarbazones and semicarbazones [13,[18][19][20]. On heating, all the complexes decomposed and did not present a clear melting point.…”

“…The cobalt complex (2) shows a peak at 310 nm and two peaks in the visible region at 607 and 671 nm (16,475 and 10,300 cm )1 ) corresponding to pseudo-tetrahedral geometry [15,25]. Compound (3) leads to an intense absorption at 300 nm followed by two weak peaks at 800 and 1015 nm (12,500 and 9,850 cm )1 ) typical of square planar and/or tetrahedral species [24][25][26].…”

We have prepared and characterised a new series of metal complexes obtained from 4,4¢-bis(salicylideneimino)diphenylethane (saldipH 2 ) and cobalt(II), copper(II) and cadmium(II) chlorides. In every case, the coordinating atoms are N and O. However, each compound has its own structure: [Co(saldip)] AE 2 H 2 O is monomeric and a mononuclear species, [Cu 2 (saldip) 2 (H 2 O)] is a binuclear complex and finally the cadmium complex is formulated as: [(CdCl 2 ) 2 (saldipH 2 )] AE CdCl 2 . An electrochemical study (cyclic voltammetry) indicates that the reduction, as well as the oxidation, of copper in [Cu 2 (saldip) 2 (H 2 O)] proceeds in two steps. For the reduction of the two other complexes, two steps are indicated out: the first is attributed to the reduction of the metal and the second to the reduction of the coordinated ligands.

“…Semicarbazones are reported to possess versatile structural features 6 and very good antifungal and antibacterial properties 7,8 . The spectral properties of some furfuraldehyde semicarbazone and 2-hydroxyacetophenone N(4)-phenyl semicarbazone were recently reported 9,10 . No report is available in the literature on mixed ligand complexes of dioxouranium(VI) with semicarbazones derived from 4-aminoantipyrine and diphenyl sulfoxide.…”

In the present work, the authors describe the synthesis of some mixed ligand complexes of thorium(IV) derived from 4[N-(2'-hydroxy-1'-naphthalidene)amino]antipyrine semicarbazone (HNAAPS) or 4[N-(cinnamalidene)amino]antipyrinesemicarbazone (CAAPS) as primary ligand and diphenyl sulfoxide (DPSO) as secondary ligand with the general composition ThX 4 .n(L).DPSO (n = 1, X = Cl, Br, NCS or NO 3 ; n = 2, X = I or ClO 4 , L = HNAAPS or CAAPS). All the compounds were characterized through elemental analysis, molar conductance, molecular weight, infrared data and thermogravimetric analysis. The infrared studies reveal that the semicarbazones behave as neutral tridentate (N,N,O) while DPSO coordinates through its oxygen atom. The nitrates are bicovalently bonded, while thiocyanates are N-coordinated in these compounds. In conclusion, the coordination number of the central metal ion displays coordination number 7, 8, 9 or 12 depending on the nature of the anionic ligands.
