Synthesis and Characterisation of Dialkyl[2-(2-phenolato)Oxazolines] of Gallium(III) and Indium(III): Crystal Structure of [{InMe 2 (OC 6 H 4 -OxMe 2 )} 2 ]
Reactions of trialkylgallium/indium etherate with 2-(2-hydroxyphenyl)oxazolines afforded colourless dialkyl[2-(2-phenolato)oxazoline]gallium/indium complexes of the type [GaR2(OC6H4-OxR′R″)] (1) and [{InMe2(OC6H4-OxR′R″)}2] (2) (R = Me or Et; Ox = oxazoline, R′ = Me or Et; R″ = Me or H). These complexes were characterised by elemental analysis, IR, mass and NMR (1H and 13C) spectral data. The complex [{InMe2(OC6H4-OxMe2)}2] has a dimeric structure as established by X-ray diffraction. The indium atom acquires an irregular trigonal bipyramidal geometry defined by C2O2N ligating atoms.
