Four 1,2-diamine ligands, (1RS,2SR)-1-methyl-1,2-cyclohexanediamine(1m-chxn), (1R,2S,3R)-3-methyl-1,2-cyclohexanediamine(R,S,R-3m-chxn), (1S,2R,4R)-4-methyl-1,2-cyclohexanediamine(S,R,R-4m-chxn), and (1R,2S,4R)-4-methyl-1,2-cyclohexanediamine(R,S,R-4m-chxn), were prepared. The mixed-ligand complexes of the [PtXL]2+ type(X=(NH3)2, 1,2-ethanediamine, meso-2,3-butanediamine, and 2,3-dimethyl-2,3-butanediamine
四个 1,2-二胺配体,(1RS,2SR)-1-甲基-1,2-环己二胺(1m-chxn),(1R,2S,3R)-3-甲基-1,2-环己二胺(R,S ,R-3m-chxn)、(1S,2R,4R)-4-甲基-1,2-环己二胺(S,R,R-4m-chxn)和(1R,2S,4R)-4-甲基-制备了1,2-环己二胺(R,S,R-4m-chxn)。[PtXL]2+型(X=(NH3)2、1,2-乙二胺、meso-2,3-丁二胺和2,3-二甲基-2,3-丁二胺,L=每个 m-chxn) 被合成并通过它们的电子、圆二色性和 13C NMR 光谱表征。S,R,R-4m-chxn形成的螯合环几乎构象固定为δ构象,而1m-chxn、R,S,R-3m-chxn和R,S,R的螯合环-4m-chxn 很容易在 δ 和 λ 构象之间互换。
