Because of its cross-bridged topology it exhibits a relatively rigid preorganized conformation especially appropriate to complex formation, as shown by the crystal structure of the monoprotonated ligand salt, HL1ClH2O [orthorhombic, P212121, a = 9.4405(5) A, b = 13.3617(5) A, c = 16.710(1) A]. The complexes of L1 with both iron(II) and manganese(II) have been characterized, including the crystal structures
合成了新型的双环五齿配体5-甲基-1,5,9,24,25-五氮杂五环[7.7.7.5.5]戊二十烷11,13,15,18(25),20,22-己烯(L1)。由于其跨桥拓扑结构,它表现出相对较硬的预组织构象,特别适合于复合物的形成,如单质子化配体盐HL1ClH2O的晶体结构所示[斜方晶系,P212121,a = 9.4405(5)A,b = 13.3617( 5)A,c = 16.710(1)A]。L1与铁(II)和锰(II)的配合物已被表征,包括[FeL1CH3CN] [FeCL4]和[MnL1Cl] [PF6]的晶体结构[单斜晶系,P21 / n,a = 10.0460(5) A,b = 19.237(9)A,c = 15.6254(8)A,beta = 95.97(2)度,a = 7.745(2)A,b = 22.786(4)A,c = 14.639(4)A, beta = 105.0
