bis-monodentate bridging mode in complex 1, whereas HL2 adopts monodentate and bidentate bridging modes in 2 and a tridentate bridging mode in 3. The chelating ligands phen and pp give rise to a 1D zigzag chain in complexes 1 and 3, and a binuclear structure in 2, by preventing the formation of higher-dimensional structures. Notably, the anions play an important role in the structure of complex 3. In addition, the
摘要 三种金属有机配合物与两个蒽基庞大的骨架配体 9,10-dioxo-9,10-dihydroanthracene-1,5-二羧酸 (H2L1) 和 2-苯基喹啉-4-羧酸 (HL2),即 [Mn(L1)0.5(L1)0.5(phen)(H2O)2](H2O)1.5}∞ (1), [Mn2(L2)4(phen)2(H2O)2](H2O)2 (2)和 [Cd3(L2)2(pp)2Cl4]∞ (3) (phen = 1,10-菲咯啉, pp = 3-(2-pyridyl)pyrazole),已被合成和表征。X 射线单晶衍射表明 H2L1 在配合物 1 中采用双单齿桥接模式,而 HL2 在配合物 2 中采用单齿和双齿桥接模式,在 3 中采用三齿桥接模式。螯合配体 phen 和 pp 产生一维通过阻止高维结构的形成,复合物 1 和 3 中的锯齿形链和 2 中的双核结构。尤其,阴离子在配合物 3
