six-membered chelate metallocycles in a twist-boat conformation. The diagonal arrangement of “soft-hard” donor atoms (S–M–Cl, C–M–Cl) in the coordination sphere leads to the Pearson's effect of “molecular antisymbiosis in the trans effect” that causes the formation of complexes with an M:L ratio of 1:1. However, interaction in the ratio 1:2, 1:3 is also possible in the solution under the conditions of monodentate
PdCl 2或K 2 [PtCl 4 ]与N , N反应得到四种单核n,π-螯合物[ M (HL 1,2 )Cl 2 ] ( M = Pd 2+ , Pt 2+ ) -二乙基-N' -(2-丙烯基)硫脲(HL 1 )或N-环己基-N' -(2-丙烯基)硫脲(HL 2 )在HCl存在下。根据 X 射线衍射研究,HL 1,2的分子以双齿方式与扭船构象中的六元螯合金属环的形成协调。“软-硬”供体原子(S-M-Cl、C-M-Cl)在配位层中的对角排列导致“反式效应中的分子反共生”的皮尔逊效应,导致形成具有M:L 比例为 1:1。然而,在HL 1和HL 2单齿配位的条件下,溶液中也可以1:2、1:3的比例相互作用。所有化合物均通过 IR、UV-Vis 和 NMR 光谱进行了研究。1小时/ 13C NMR 研究表明,该方法对于建立 π 配位键的形成是可靠的。合成的复合物结构与顺铂的相似性意味着它们的抗
