Nuclear quadrupole resonance of Co59 of certain organobimetallic carbonyl complexes containing Ge-Co and Sn-Co bonds

Abstract

1. The NQR spectra of Co59 of a number of organobimetallic carbonyl complexes, containing Ge-Co and Sn-Co bonds, were investigated. 2. It was found that eQqzz of Co59 increases with increasing electronegativity of the substituents at the germanium and tin atoms. 3. It was shown by the method of two-parameter correlations of the quadrupole coupling constants with the induction and conjugation characteristics of the substituents that there is some multiplicity of the Sn-Co bond in the series R'R2SnCo(CO)4.
