The complex cations [RuL2(H2biim)]2+ (L=bipy, 4,4'-tBu2-bipy) interact with cyanometallate anions via a chelating hydrogen-bonding interaction between the two N-H donors of the complex cation and the N lone pair of one cyanide ligand in the complex anion; the anion hexacyanoferrate(III) quenches the Ru(II)-based luminescence in CH2Cl2 solution by photoinduced electron-transfer within the H-bonded assembly, whereas hexacyanocobaltate(III) enhances the Ru(II)-based luminescence.
配合物阳离子[RuL₂(H₂biim)]²⁺(L = 联吡啶,4,4'-二叔丁基联吡啶)通过配合物阳离子的两个N-H供体与配合物阴离子中一个氰化物配体的N孤对之间的螯合氢键相互作用与氰基金属酸盐阴离子相互作用;在二氯甲烷溶液中,六氰合铁(III)酸盐阴离子通过氢键组装体内的光致电子转移猝灭基于Ru(II)的发光,而六氰合钴(III)酸盐则增强基于Ru(II)的发光。
