Bonding in Boron Hydrides
Unique preferred localized valence structures for B2H6, B4H10, B5H,, and B6H10 have been found from accurate self-consistent field wavefunctions by maximizing Coulomb repulsions of electron pairs within orbitals. Objective evidence has thus been obtained for two-centre BH, three-centre bridge BHB, two-centre BB and central three-centre BBB bonds, but not, as yet, for open three-centre BBB bonds...
متن کاملIntramolecularly Sn–N Coordinated Organotin Hydrides
In recent years, internally Sn–N coordinated organotin hydrides have found an application in organic syntheses, which involve radical chain reactions. Unique reactivity of such hydrides suggests the potential of intramolecular coordination for the control of radical reactions. When the tin hydrides are used in the presence of Lewis acids single-enatiomer outcomes are accessible. This opens a ne...
متن کاملOn the Hydrides of B, C, N, O and F
I have had thoughts on the hydrides possible for B, C, N, O & F, and particularly for N there seems to be some interesting undiscovered possibilities. Thus I am aware of: (1) the hydrides of B have been investigated & elucidated by Stock et al. and Lipscomb et al. & I have tried to read this literature, but I am not able to get a reliable source, and I understand that the hydrides of B differ f...
متن کاملThe Influence of Silicon and Boron on the Electrochemical Behaviour of Ab,-hydrides
AB,-type intermetallic compounds were prepared by induction melting and melt spinning. The composition of a stoichiometric compound LaNi,,,Co,.,Mn,,,Al,.~ with a hexagonal CaCu, structure was varied by &i&&metric and nonstoichiometric addition of Si and B. Discharge capacity is increased considerabdy by addition of silicon in the range of 0.5-5 at% with a maximum value at about 1%. The highest ...
متن کاملIupac Theoretical and Structural Studies on Organometallic Cluster Molecules
ABSTR,6CT. The development of topological rules for hydrido-metal cluster compounds, similar to those proposed by Lipscomb for boron hydrides, is shown to be a direct consequence of the multicentre bonding in bridged hydrido-metal bonds. Evidence for this localised view of the bonding has been obtained from U.V. photoelectron spectral studies of the hydridocarbonyl cluster compounds Re3(CO)12H3...
