6-bis(4′-tBuC6H3)2pyridine dianion). The reactions of (C∧Npz∧C)AuOAcF (7a) and (C∧Npy∧C)AuOAcF (7b) with MeMgI gave the methyl complexes (C∧Npz∧C)AuMe (8a) and (C∧Npy∧C)AuMe (8b), respectively. The crystal structures of 2a,b, 3a, 6a, and 7a have been determined. The photophysical properties of the new complexes and those of the previously reported gold hydride (C∧Npz∧C)AuH (AuH) are reported. The lower-energy absorption
