Sulphidomolybdenum(V) complexes with amino acid dithiocarbamates
摘要:
The interaction of ammonium tetrathiomolybdate with the barium salts of the dithiocarbamates (dtc) of glycine, DL-alanine and DL-2-aminobutyric acid yielded Ba[Mo2S4(dtc)2]. The molar conductivities (approximately 50 OMEGA(-1) cm-1) in DMSO indicated the ionic nature of the complexes. The subnormal magnetic moment (0.4 B.M.), electronic and IR spectral data and CVM peak potentials (-0.95 and -1.25 V vs SCE) suggested a dimeric species with a [Mo2S4]2+ core. The IR spectral data suggested the bidentate coordination of the dithiocarbamate groups and the absence of coordination by the carboxylate group. Thermal properties of the complexes are discussed.

Lanthanum(III) and praseodymium(III) complexes with dithiocarbamates have been synthesized by the reactions of lanthanum(III) and praseodymium(III) chloride with barium dithiocarbamate and complexes of type [LnCl(L)H2O]n have been obtained (where Ln=La(III) or Pr(III); L=barium salt of dithiocarbamate derived from glycine, L-leucine, L-valine, DL-alanine). The complexes have been characterized by elemental
通过镧(III)和氯化ase(III)与二硫代氨基甲酸钡的反应合成了镧(III)和ase(III)配合物,得到了[LnCl(L)H2O] n类型的配合物(其中Ln = La(III)或Pr(III); L =衍生自甘氨酸,L-亮氨酸,L-缬氨酸,DL-丙氨酸的二硫代氨基甲酸酯的钡盐)。通过元素分析,摩尔电导,电子吸收和荧光,红外,远红外,1H NMR光谱研究对复合物进行了表征。从热重分析可以推断出配位水分子的存在,这表明一个水分子在150-170摄氏度时会损失。对于不同的跃迁,已经获得了振荡器强度,Judd-Ofelt强度参数,受激发射截面等。 Pr3 +。
