General description

Cobalt(II) oxo pivalate is a dinuclear complex that is typically formed by the direct reaction of cobalt carbonate with pivalic acid, followed by crystallization from MeCN. Its structure has two Co(II) sites bridged by two 2,11-carboxylates (Harris notation) and an oxygen atom.
