Synthese und Kristallstrukturen von Dimethylgalliumdiphenylphosphinat und Diethylindiumdiphenylphosphinat / Synthesis and Crystal Structures of Dimethylgalliumdiphenylphosphinate and Diethylindiumdiphenylphosphinate

Abstract

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. [Ph 2 P(O) 2 Ga(CH 3 )] 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). [Ph 2 P(O) 2 In(C 2 H 5 )2] 2 crystallizes monoclinically, C2/c, with a = 19.971(5), b = 8.590(2), c = 19.457(5)Å, β = 102.91(2)° and Ζ = 4 (dimers). Both structures contain tetrahedrally coordinated phosphorous and metal atoms.
