Mixed Valency in Inorganic Chemistry [PDF]

open access: possible, 1984
The aim of these lectures is to survey the occurrence of mixed oxidation states in inorganic compounds throughout the Periodic Table and to show how chemists have sought to relate structures to physical properties. We shall focus on the extent of electron delocalization between ion sites, and the extent to which it is determined by ligand field ...

Geminal-based electronic structure methods in quantum chemistry. Toward a geminal model chemistry.

Physical Chemistry, Chemical Physics - PCCP, 2022
In this review, we discuss the recent progress in developing geminal-based theories for challenging problems in quantum chemistry. Specifically, we focus on the antisymmetrized geminal power, generalized valence bond, antisymmetrized product of strongly ...

Mixed-Valence Ce-BPyDC Metal-Organic Framework with Dual Enzyme-like Activities for Colorimetric Biosensing.

Inorganic Chemistry, 2019
Enzyme-like metal-organic frameworks (MOFs) are currently one type of starring material in the fields of artificial enzymes and analytical sensing. However, there has been little progress in making use of the MOF structures based on the catalytically ...

Valence bond theory in coordination chemistry

Journal of Chemical Education, 1962
The author disagrees that the valence bond theory has suffered a rapid fall from favor, and that there has been a consequent rise in esteem of the molecular orbit and crystal field theories.

Mixed Valence in Chemistry

1987
Mixed valence is as old as chemistry itself, Prussian blue, Fe4 [Fe(CN)6]3 14H2O and magnetite, Fe3O4, being well-known examples. Mixed valence chemistry comprises a variety of solids formed by a third of the elements in the periodic table and the subject has assumed great importance in recent years1,2.

Valence Bond Theory in Heterocyclic Chemistry

2014
This chapter deals with the application of valence bond theory in heterocyclic chemistry. A short introduction to the different valence bond methods is given, followed by illustrative results obtained by valence bond calculations. The illustrations show the applicability of the valence bond theory to obtain detailed information on the electronic ...
