ligand was identified by mass spectra, NMR and FT-IR spectra. The optimization conditions of pH, time of reaction, and the molar ratio (M:L) were estimated in order to get the pure colored solid complexes chromium(III), molybdenum(II), nickel(II), palladium(II) and platinum(II) by the direct reactions of their metal chlorides in aqueous methanol with the ethanol solution of the ligand. The geometrical
最近的论文涉及具有混合双齿配体即[3,5-二甲基-1H-]的铬(III),钼(II),镍(II),钯(II)和铂(II)配合物的合成和表征研究。吡唑-1-甲硫酰胺和2,2-联吡啶]是通过在2-正盐酸中酸化乙酰丙酮与硫代氨基脲一起闭环制得的。通过质谱,NMR和FT-IR光谱鉴定了新的2-吡唑啉基配体。估算了pH,反应时间和摩尔比(M:L)的最适条件,以获得纯色固体配合物铬(III),钼(II),镍(II),钯(II)和铂(II)通过其金属氯化物在甲醇水溶液中与配体的乙醇溶液直接反应而制得。金属配合物的几何结构通过电子,红外光谱的测量以及磁化率和摩尔电导率的测量得到证实。从元素分析和其他光谱数据获得的结果表明,所有配合物的八面体几何形状都不同,除了钯(II)配合物在[PdL(bipy)] Cl2式中为方形规划剂之外。
