These prototypical monomers may be systematically extended in size yielding a novel quasi 1ヾimensional, strongly correlated model system consisting of cobalt atoms bridged by oxygen atoms and fluorine termination on both ends. Accurate correlation energies are obtained using Full Configuration ...

The neutral complexes (60) and (62) are paramagnetic and have the same rare 19-electron configuration as cobaltocene whereas (61) is a diamagnetic 18-electron cation. Sign in to download full-size image This unique borylene insertion may be rationalized (Scheme 7) with reference to well ...
The configuration of the outer electron shells of a cobalt atom is 3d74s2. In compounds cobalt exhibits alternating valence. In simple compounds, Co (II) has the highest degree of stability, and Co (III) is most stable in complex compounds. Only a few complex compounds of Co (I) and Co...
Anson, Collman, and co-workers have published a series of papers using bridged dicobalt “face-to-face” porphyrins, some of which are efficient catalysts of the four-electron reduction of O2 to H2O.263,264 Participation of both Co ions in O2 binding (in a sandwich configuration) and in...

Mg3P2O8(with Mg1-O distances between 1.969 and 2.150 Å according to the ICSD-261231 data). The differences in the electron configuration with the seven electrons in the 3d orbitals in the Co(II) ion and with a small orbital penetration effect could explain the fact that the Co-O ...
