Metal to metal multiple bonds in ordered assemblies

Metal-metal bonds in bimetallic surfaces.

The usefulness of EPR spectroscopy in the study of compounds with metal-metal multiple bonds.

This Perspective reviews some of the contributions that EPR spectroscopy has made for the understanding of the bonding and electronic structure of molecular species with metal-to-metal multiple bonds. The goal is to show how useful this technique can be in (a) elucidating whether unpaired electrons reside in metal-based or ligand-based molecular orbitals, (b) providing information on the metal ...

How Carbon Monoxide Bonds to Metal Surfaces

An analysis is presented of the similarities and differences in the bonding of CO to Ni(100), Ni(l1 l ) , Co(OOOl), Fe(1 lo), Cr(llO), and Ti(0001). The primary interactions in every case are the expected forward and back donation, the mixing of CO 5u with surface dzz and s states, and the mixing of CO 2a with metal dxryz. The latter interaction is dominant. Projections of the density of states...

Technetium dichloride: a new binary halide containing metal-metal multiple bonds.

Technetium dichloride has been discovered. It was synthesized from the elements and characterized by several physical techniques, including single crystal X-ray diffraction. In the solid state, technetium dichloride exhibits a new structure type consisting of infinite chains of face sharing [Tc(2)Cl(8)] rectangular prisms that are packed in a commensurate supercell. The metal-metal separation i...
