Synthesis, NMR Spectra and Structure of [(CH 3 ) 2 Ga{μ‐P(H)Si(CH 3 ) 3 } 2 Ga(CH 3 ) 2 {μ‐P(Si(CH 3 ) 3 ) 2 }Ga(CH 3 ) 2 ] 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.
