The present invention provides 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. 本文提供了不对称双(唑鎓)盐、不对称CCC-NHC金属配合物及其形成方法。所述不对称双(唑鎓)盐包括中心芳环，所述中心芳环被两个杂环以邻位、间位或对位方式取代。所述不对称CCC-NHC金属配合物包括金属化的不对称双
