Nuclear magnetic resonance study of the solvation behaviour of cobalt-(II) halides in non-aqueous solvents

Abstract

The variable-temperature ¹H n.m.r. behaviour of cobalt(II) halides has been studied in solvents of different basicities. The solvents were acetone, acetonitrile, acrylonitrile, and dimethyl sulphoxide. Coupling constants have been derived for each solvated species and comparison is made, where possible, with previous work. The behaviour of some systems was simulated using solvolytic equilibria.
