The tri‐cationic shell gallium complex [Ga(CH 2 (P(O)Ph) 2 ) 3 ] 3+ containing three neutral diphosphine oxide ligands has been synthesized and structurally characterized by using X‐ray crystallography, mass spectrometry, and 1 H, 13 C, 31 P, and 71 Ga NMR spectroscopy. The ligands form three equivalent six‐membered chelate cycles to give an idealized octahedral environment around the Ga 3+ ion. This compound is the first example of a mononuclear homoleptic octahedral structure formed by neutral phosphine oxide ligands in the chemistry of the 13 group elements in the +3 oxidation state.
