1. A hexacoordinate complex comprising:
a central atom selected from the group consisting of silicon, germanium, and tin; and
two pincer ligands bound to the central atom, wherein the hexacoordinate complex is luminescent, wherein the pincer ligands are dianionic and at least one binding site of the pincer ligands comprises a heteroaryl moiety, and wherein the hexacoordinate complex has a quantum yield greater than 50 percent when measured in THE at room temperature.
