摘要
摘要基于核磁共振波谱和单晶X射线，描述了羰基碳硼烷衍生物9-XCH2S(Me) s -7,8- c2b9h11和10-RC≡CCH2S(Me) s -7,8- c2b9h11中新型分子内B-H⋅⋅X氢化物卤素和B-H⋅⋅⋅π(C≡C)氢键的形成，以及钴二(二)羰基配合物[3,3′-M(1,2- c2b9h11)2] -中二羰基配体之间的分子内氢键在不同旋转异构体(旋转体)稳定中的作用研究。
Intramolecular non-covalent interactions in nido-carboranes and metallacomplexes
GRAPHICAL ABSTRACT ABSTRACT The formation of new types of intramolecular B-H⋅⋅⋅X hydride-halogen and B-H⋅⋅⋅π(C≡C) hydrogen bonds in nido-carborane derivatives 9-XCH2S(Me)S-7,8-C2B9H11 and 10-RC≡CCH2S(Me)S-7,8-C2B9H11 as well as the role of intramolecular hydrogen bonding between the dicarbollide ligands in cobalt bis(dicarbollide) complexes [3,3′-M(1,2-C2B9H11)2]− in stabilization of their different rotational isomers (rotamers) were described based on NMR spectroscopy and single-crystal X-ray studies.
