| Abstract: | Synthesis, NMR Spectra and Structure of [(CH3)2Ga{μ‐P(H)Si(CH3)3}2Ga(CH3)2{μ‐P(Si(CH3)3)2}Ga(CH3)2] The title compound has been prepared in good yield by the reaction of [Me2GaOMe]3 (Me = CH3) with HP(SiMe3)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(SiMe3)2–Ga and two Ga–P(H)SiMe3–Ga bridges and crystallizes in the monoclinic space group C2/c. The known homologous Al‐compound is isotypic, both (MIII–P)3 heterocycles have twist‐conformations, the ligands of the monophosphane bridges have trans arrangements. |
