The synthesis of a new, paramagnetic closo-[(8-(-CH2CH2O)2-1,2-C2B9H10)(1′,2′-C2B9H11)-3,3′-Fe]0 (3) is reported. This compound can serve as a versatile building block for construction of both anionic and zwitterionic derivatives, as exemplified by the synthesis of a series of compounds of general formula closo-[(8-X-(CH2CH2O)2-1,2-C2B9H10)(1′,2′-C2B9H11)-3,3′-Fe], bearing organic end groups (X = NC5H5
新的顺磁性梭菌-[(8-(-CH 2 CH 2 O)2 -1,2-C 2 B 9 H 10)(1',2'-C 2 B 9 H 11)-3的合成,3'-Fe] 0(3)被报道。该化合物可以用作构建阴离子和两性离子衍生物的通用结构单元,例如,合成了一系列通式为closo -[(8-X-(CH 2 CH 2 O)2 -1, 2-C 2 B 9 H 10)(1′,2′-C2 B 9 H 11)-3,3'-Fe],带有有机端基(X = NC 5 H 5(4),(C 6 H 5)3 P(5),OH(6)和2- O(1-CH 3 O–C 6 H 4)(7))通过二甘醇间隔基连接到簇。的分子结构3,4,5和7是由单晶X射线衍射分析,并通过NMR(顺磁性的,高场的长时间被忽视的方法测定的1 H,13 C和11 B)光谱。
