Provided herein are unsymmetrical bis(azolium) salts, unsymmetrical CCC—NHC metal complexes, and methods of forming the same. The unsymmetrical bis(azolium) salts include a central aryl ring that is substituted with two heterocyclic rings in an ortho, meta, or para fashion. The unsymmetrical CCC—NHC metal complexes include metalated unsymmetrical bis(azolium) salts. The method of forming the unsymmetrical CCC—NHC metal complexes includes reacting a dihalogenated benzene with a first azole to form a mono(azole)benzene, reacting the mono(azole)benzene with a second azole to form an unsymmetrical bis(azole)benzene, alkylating the unsymmetrical bis(azole)benzene to form an unsymmetrical bis(azolium) salt, and metalating the unsymmetrical bis(azolium) salt to form the unsymmetrical CCC—NHC metal complex. Also provided are a bis-ligated CCC—NHC metal complex and an unsymmetrical bimetallic complex.
