We report the synthesis and structure determination of a new Au22 nanocluster coordinated by six bidentate diphosphine ligands: 1,8-bis(diphenyl­phosphino) octane (L8 for short). Single crystal X-ray crystallography and electrospray ionization mass spectrometry show that the cluster assembly is neut...
