A mixed-valence cobalt(I)-cobalt(II) complex containing a bridging sodium cation
Abstract
Sodium [N,N′-ethylenebis(salicylideneaminato)]cobaltate(I), [Co(salen)Na(thf)]n(thf = tetrahydrofuran), reacts with the cobalt(II) parent complex [Co(salen)] to form a neutral mixed-valence CoI–CoII complex in which two identical [Co(salen)] units act as equatorial ligands for a Na+ cation completing its octahedral co-ordination sphere with two thf molecules trans to each other.
