Six-co-ordinated mono-, bis-, and tris-(monothio-β-diketonates) of iridium(III) have been synthesized and character ized. The X-ray crystal structure of the title compound reveals a distorted octahedral geometry with facia I arrangement of the sulphur and oxygen ligand atoms.
Six-coordinated tris(monothio-β-diketonates) of Tc(III) and Re(III) have been synthesized by the reaction of M(III) thiourea complexes with the appropriate monothio-β-diketone ligands in methanol. Characterization of the compounds by IR, UV-Vis, 1H NMR and mass spectroscopy indicates that the ligands coordinate as bidentate. The 1H NMR spectra of the paramagnetic substances are well resolved and the
Tc(III)和Re(III)的六配位三(单硫代-β-二酮)(三价)是通过M(III)硫脲络合物与适当的单硫代-β-二酮配体在甲醇中的反应合成的。通过IR,UV-Vis,1 H NMR和质谱对化合物的表征表明,配体作为二齿配位。顺磁性物质的1 H NMR光谱得到很好的解析,螯合环质子显示Tc复合物的大高场频移和相应的Re类似物的低场频移。在三(单硫代二苯甲酰基甲基甲烷)tech(III)上进行的完整晶体和分子结构测定,是具有O和S螯合配体的Tc(III)化合物的首次结构表征。
