The thermal behaviour of the complexes of N,N-diethyl-N′-benzoylthiourea (DEBT) with Ni(II), Cu(II), Pt(II), Pd(II) and Ru(III) was studied using differential thermal analysis (DTA) and thermogravimetry (TG). These complexes undergo only a pyrolytic decomposition process. A gas chromatography-mass spectrometry combined system was used for the verification of the first decomposition product and X-ray diffraction method for the characterization of the final products of pyrolysis.

photonic and optoelectronic technologies. New NLO frequency conversion materials have a significant impact on laser technology and optical data storage [ 9 ]. Thiourea is an interesting inorganic matrix modifier due to its large dipole moment and its

, metal complexes of thiourea have low cutoff wavelengths, applicable for high-power frequency conversion [ 1 ]. Thiourea is a centro-symmetric molecule. When it is coordinated with metal ions, it becomes non-cento-symmetric material and exhibits non

Abstract  

Zinc carboxylates complexed with N-donor ligands have potential antifungal effects. The preparation, identification and especially the thermal properties of four hitherto non-characterized compounds of this group of general formula (CH3CH2COO)2Zn·2L·H2O are described in this paper. The experimental results are confronted with present knowledge on analogous compounds.
