Structure and Bonding in Planar Hypercoordinate Carbon Compounds

Magnetism, Bonding and Structure of Coordination Compounds

INTRODUCTION It is not only timely, for the reasons discussed below, to provide a survey of the use of magnetic susceptibility measurements for the study :of complex compounds, but also fitting that the subject should be discussed in a country whose scientists have made so many outstanding contributions to quantum mechanics in general and spectroscopy and magnetism in particular. I pay a specia...

Intermetallic Compounds of Element 112: the Electronic Structure and Bonding

The next heaviest element which is to be studied chemically at the JINR, Dubna, [1] and GSI [2] is element 112. Its properties are expected to be unique: high volatility and inertness due to the very strong relativistic stabilization of the 7s electrons and the closed-shell configuration, 7s6d [3]. The surface of the chromatography column in the gas-phase chromatography experiments is to be mad...

Computational design of organometallic oligomers featuring 1, 3-metal-carbon bonding and planar tetracoordinate carbon atoms

Density functional theory computations (B3LYP) have been used to explore the chemistry of titanium-aromatic carbon "edge complexes" with 1,3-metal-carbon (1,3-MC) bonding between Ti and planar tetracoordinate Cβ . The titanium-coordinated, end-capping chlorides are replaced with OH or SH groups to afford two series of difunctional monomers that can undergo condensation to form oxide- and sulfid...

Photoelectron Spectra and Bonding in Phosphorus Compounds'

The results of (low energy) photoelectron spectroscopy render possible a better appreciation of bonding in molecules. The application of the new experimental method is demonstrated utilizing representative phosphorus compounds, and the close symbiosis delineated with molecular orbital models. Among the topics discussed are: the element P4, phosphine PH3 and derivatives, phosphorus substituent e...
