-(7 0 -chloroquinolin-4 0 -ylamino)thiosemicarbazide with 2-hydroxybenzaldehyde. The structures of the complexes were determined on the basis of the elemental analyses, spectroscopic data (IR, electronic, 1 H and 13 C NMR and Mass spectra) along with magnetic susceptibility measurements, molar conductivity and thermogravimetric analyses. Electrical conductance measurement revealed the non-electrolytic nature of the complexes. The resulting colored products are mononuclear in nature. On the basis of the above studies, only one ligand was suggested to be coordinated to each metal atom by thione sulfur, azomethine nitrogen and phenolic oxygen to form mononuclear complexes in which the thiosemicarbazone behaves as a monobasic tridendate ligand. The ligand and its metal complexes were tested against Gram þ ve bacteria (Staphylococcus aureus), Gram 2 ve bacteria (Escherichia coli), fungi (Candida albicans) and (Fusarium solani). The tested compounds exhibited significant activity.

The Schiff base ligand, oxalic bis[(2-hydroxybenzylidene)hydrazide], H 2 L, and its Cu(II), Ni(II), Co(II), UO 2 (VI) and Fe(III) complexes were prepared and tested as antibacterial agents. The Schiff base acts as a dibasic tetra-or hexadentate ligand with metal cations in molar ratio 1:1 or 2:1 (M:L) to yield either mono-or binuclear complexes, respectively. The ligand and its metal complexes were characterized by elemental analyses, IR, 1 H NMR, Mass, and UV-Visible spectra and the magnetic moments and electrical conductance of the complexes were also determined. For binuclear complexes, the magnetic moments are quite low compared to the calculated value for two metal ions complexes and this shows antiferromagnetic interactions between the two adjacent metal ions. The ligand and its metal complexes were tested against a Gram þ ve bacteria (Staphylococcus aureus), a Gram -ve bacteria (Escherichia coli), and a fungi (Candida albicans). The tested compounds exhibited high antibacterial activities.

“…New strong split bands with maxima at 1127, 1064 and 985 cm À1 for the Pr complex and at 1139, 1072 and 994 cm À1 for the Gd complex were observed. This band may be attributed to S-bonded coordination [56][57][58]. Based on the above thermal data, the following decomposition mechanism was proposed for Ln-Pen: ½Gd:Pen:NO 3 ffi 2H 2 O À 55 C !…”

The complex-formation of lanthanide(III) elements with D-penicillamine have been investigated in acidic and neutral media. The macroscopic protonation constants of the ligand and the formation constants of [Ln.Pen] þ , [Ln.Pen 2 ] À , [Ln.Pen.OH] and [Ln.Pen.(OH) 2 ] À complexes were determined from pH-metric data using the BEST computer program. Elemental analyses of the solid complexes indicate formation of 1 : 1 metal : ligand species. The binding sites in the complexes with the possible role of -COO À , -NH 2 and -SH groups in the coordination have been discussed using infrared data. The complexes decompose in four steps as shown by their t.g. and d.t.a. analyses. A mechanism of decomposition is proposed which is supported by mass spectral data.
