Synthesis, Characterization, and Thermal Decomposition of [Cl2 GaP(SiMe3 )2 ]2 , a Potential Precursor to Gallium Phosphide
[Cl2GaP(SiMe3)2]2 (1) has been prepared from the 1:1 reaction of GaCl3 with P(SiMe3)3. Thermal decomposition of 1 produces a brown powder which contains GaP, as evidenced by an X-ray powder pattern and partial elemental analysis. Compound 1 crystallizes in the monoclinic space group P21/n (No. 14) with a = 9.754(2) Å, b = 15.585(5) Å, c = 9.839(2) Å, and β = 96.18(1)°, is composed of a planar [formula omitted], with GaP bond distances of 2.378(2) and 2.380(2) Å, and contains exocyclic chlorine and SiMe3 ligands. The ring core is a slightly distorted square, with GaPGa′ and PGaP′ bond angles of 86.41(7) and 93.59(7)°, respectively. Additionally, 1H NMR confirms that 1 exhibits monomer—dimer equilibrium in solution. © 1993, American Chemical Society. All rights reserved.
