✦ Synopsis

The title compound has been prepared in good yield by the reaction of [Me 2 GaOMe] 3 (Me = CH 3 ) with HP(SiMe 3 ) 2 in toluene (ratio 1 : 1,1) and purified by crystallization from pentane or toluene, respectively. This organogallium compound forms (Ga±P) 3 ring skeletons with one Ga±P(SiMe 3 ) 2 ±Ga and two Ga±P(H)SiMe 3 ±Ga bridges and crystallizes in the monoclinic space group C2/c. The known homologous Al-compound is isotypic, both (M III ±P) 3 heterocycles have twist-conformations, the ligands of the monophosphane bridges have trans arrangements.
