A hexanuclear gold(I) selenido cluster and its sulfido counterpart, [Au 6 {μ‐Ph 2 PN(CH 2 ‐ o ‐Py)PPh 2 } 3 (μ 3 ‐E) 2 ](ClO 4 ) 2 (E = S, Se), with bridging bis(diphenylphosphino)amine ligands were synthesized and characterized. The X‐ray crystal structure of the selenido cluster was determined, with the gold core possessing a distorted heterocubane structure. Intramolecular aurophilic interactions with short Au(I)⋯Au(I) contacts of around 3.09–3.13 Å were observed. The complexes were found to emit strongly in the solid state with orange to red emission colors. Their electronic absorption and emission properties were also investigated.
