regular π–π stacking structure while 1b has a dimer-like arrangement with a RhI–RhI distance of 3.2336(6) A. Both solids were luminescent at 77 K. Compounds 2a and 2b are planar extended π-conjugated complexes, which exhibit two-dimensional stacking modes in the crystal. The solid-state structure of complex 3 is hydrogen-bonded in a polar arrangement. The cytotoxic activities of 1a, 3, and 4, evaluated
下列铂族螯合物与 5-R-9-羟基苯酮 (L1: R = H; L2: R = Me; L3: R = Pr) 已制备: [RhI(L)(CO)2] (1a : L = L1; 1b: L = L2; 1c: L = L3), [PdII(L)2] (2a: L = L2; 2b: L = L3), [PtII(L1)(NH3)2]( NO3) (3) 和 (Bu4N)[PtII(L1)(Cl)2] (4)。化合物 1a 和 1b 在固态下是不同的颜色:分别是黄色和深红色。X 射线分析显示 1a 具有规则的 π-π 堆叠结构,而 1b 具有类似二聚体的排列,RhI-RhI 距离为 3.2336(6) A。两种固体均在 77 K 下发光。化合物 2a 和 2b 是平面的扩展的 π 共轭配合物,在晶体中表现出二维堆叠模式。配合物 3 的固态结构是氢键的极性排列。1a、3 和 4 的细胞毒活性,在体外针对
