A structural study on gallium and indium β-diketonates

Abstract

In an attempt to prepare pentacoordinate chlorobis(β-diketonato) gallium(III) and indium(III) complexes only the corresponding tris-products, Ga(PhCOCHCOPh)3 (1), Ga(tBuCOCHCOtBu) 3 (1a), and In(PhCOCHCOPh)3 (2), could be isolated. The crystal and molecular structures of 1 and 2 were determined. Both the complexes were found to have triclinc crystal system, with P1 space group. Cell parameters: 1 - a = 9.913(3) Å, b = 10.534(6) Å, c = 18.05(2) Å, α = 93.86(5)°, β = 94.40(4)°, γ = 106.58(4)°, V = 1805(2) Å3 z = 2; 2 - a = 10.507(3) Å, b = 11.448(3) Å, c = 16.322(4) Å, α = 107.38(2)°, β = 97.38(2)°, γ = 102.23(2)°, V = 1792(1) Å 3, z = 2.
