The synthesis of diethylindiumdiphenylphosphinate and the crystal structures of dimethylgalliumdiphenylphosphinate and diethylindiumdiphenylphosphinate are reported. The two structures confirm the proposed dimeric nature of the title compounds with bridging diphenylphosphinate groups. [Ph2P(O)2Ga(CH3)]2 crystallizes triclinically, PĪ, with a = 9.483(6), b = 10.216(4), c = 8.780(9)Å, α = 101.66(5)°, β = 113.74(5)°, γ = 69.93(5)° and Ζ = 1 (dimer). [Ph2P(O)2In(C2H5)2]2 crystallizes
