A significant increase in the C− O stretching force constant (F CO) and a decrease in C− O
bond length (r CO) result upon coordination of carbon monoxide to various cationic species …

Compared to the large number of CO complexes, N2 complexes are still rare. In certain
cases they may be formed from N2 gas and metal compounds under physiological …

The study of metal‐dinitrogen complexes has lent valuable insight into the nature of
dinitrogen (N2) reduction to ammonia (NH3), known as “nitrogen fixation.” Even so …

The preparation of [Ru (NH3) 5 (N2)] 2+ in 1965, 1 andthe subsequent discovery that it can
be prepared directly from dinitrogen gas, 2 ledmos't chemists to assume that dinitrogen …

The 3 molecules carbonylsilene, SiCO, and diazasilene, SiNN, have been prepared by the
vaporization and reaction of silicon atoms with N2 or CO and trapped in various matrices at …

The products of the cocondensation reactions of Ni and Pd atoms with N2 at 4.2-10 K are
investigated by matrix isolation infrared and Raman spectroscopy and are shown to be …

The process of liganddissociation from a transition metal carbonyl center has been
examined using a nonempirical molecular orbital approach. The energy requirements for …

The capabilities and limitations of approximate methods for molecular orbital (MO)~
alculations are discussed. In particular, the apparent ability of approximate methods to …

The metal dinitrogen bonding in a wide series of terminal end‐on dinitrogen complexes is
investigated with the charge displacement analysis based on natural orbitals of chemical …
