Abstract

A composition, comprising: a metal carbonyl anion; and a cation ionically bonded to the metal carbonyl anion. The cation includes a ligand and a metal centered compound. The ligand includes two residues of 3,5-substituted salicylaldehydes connected by an hydrocarbyl-diimine bridge that includes a nitrogen atom contacted with a carbon of an aldehyde residue at each of the two residues of the 3,5-substituted salicylaldehydes. Each of the residues of the 3,5-substituted salicylaldehydes are independently substituted at one or both of a 3 position and a 5 position by a hydrocarbyl group containing at least 5 carbons. The metal coordinated with the ligand at each hydroxyl residue the two residues of the 3,5-substituted salicylaldehydes at a 2 position and at each of the nitrogen atoms of the hydrocarbyl-diimine bridge. The composition includes two polar ligands coordinated with the metal.
