In an aspect, a redox flow battery comprises a catholyte and an anolyte; wherein at least one of said catholyte and said anolyte is a metal-coordination complex, said metal-coordination complex comprising: (i) a metal; (ii) one or more first ligands coordinated with said metal atom, wherein each of said first ligands is independently a Lewis basic ligand; and one or more second ligands associated with said one or more first ligands, wherein each of said second ligands is independently a Lewis acid ligand; and a nonaqueous solvent, wherein said catholyte, said anolyte or both are dissolved in said nonaqueous solvent. One or more first ligands may be provided in a primary coordination sphere of said metal-coordination complex and one or more second ligands may be provided in a secondary coordination sphere of said metal-coordination complex. The one or more first ligands independently may comprise a Lewis basic functional group and each of said one or more second ligands independently may comprise a Lewis acidic functional group.
