Reaction of {HC(CMeNAr)2}Li (Ar = 2,6-i-Pr2C6H3) with indium monochloride to yield the In-In bonded dimer [{HC(CMeNAr)2}InCl]2 and the hydroxide [{HC(CMeNAr)2}InCl(μ-OH)]2

The reaction of the sterically encumbered lithium β- diketiminate {HC(CMeNAr)2}Li (Ar = 2,6-i-Pr2C6H3) with InCl in THF at approximately -78 °C yielded In metal and [{HC(CMeNAr)2}InCl]2 (1) as well as minor amounts of the hydroxide [{HC(CMeNAr)2}In(Cl)(μ-OH)]2, 2. The compounds 1 and 2 were characterized by 1H, 13C NMR, IR spectroscopy and X-ray crystallography. The centrosymmetric structure of 1 features an In-In bond that is 2.8343(7) A? long which is well within the known range of In-In single bond distances. The metal β-diketiminate ring (i.e. C3N2In) is folded along the NN vector and features an out of plane deviation by the indium of 0.8953 A? and a dihedral angle between the C3N2 and InN2 arrays of 145.8°. This can be attributed to steric effects of the Ar groups on the β-diketiminiate ligand. The structure of the hydroxide derivative 2 is a dimer in which the indiums are bridged by hydroxides to afford a planar In2O2 core with an average In-O distance of 2.13(2) A?. Attempted reduction of the dihalide compounds {HC(CMeNAr)2}InX2 (X = Cl, I) with sodium or potassium led to the formation of metallic indium and the free β-aminoimine (Ar)NC(Me2)CHC(Me2)N(Ar)H rather than the desired In(I) species, {HC(CMeNAr)2}In:.
