(2,2'-Bi-pyridine-κ2 N , N ')di-methyl-indium iodide.

Abstract

The reaction between a tetra-meric indium-sulfide cluster [InMe4(SSiMe3)]4 (In4S4 , Me = meth-yl) and the copper dimer [CuI(bpy)]2 (bpy = 2,2'-bi-pyridine) yields the isolable title salt, [In(CH3)2(C10H8N2)]I or [InMe2(bpy)][I] (1); single-crystal X-ray diffraction, NMR, mass spectrometry, and elemental analysis confirm the structure and identity of compound 1. Computational studies involving substitution at the 6,6'-bpy positions of 1 demonstrate steric control over THF solvent binding and suggest routes to tune reactivity pertinent for Lewis acid catalysis. Details inferred from the product isolated in this specific reaction, such as the propensity of indium to form the motif [InMe2(bpy)]+ can be used to inform future studies.
