Reaction of 2 equiv of lithium dicyclohexylacetamidinate with InCl3 affords the new species In[CyNC(Me)NCy]2-Cl (Cy = cyclohexyl) (1). Compound 1 reacts with MeLi to yield In[CyNC(Me)NCy]2CH3 (2) and also reacts with a third equivalent of amidinate to yield In[CyNC(Me)NCy]3 (3). Two new bulky amidinate ligands are prepared by the addition of 1BuLi to CyN=C=NCy and Me3SiN=C=CSiMe3, respectively. Subsequent reactions with InCl3 lead to the high-yield syntheses of In[CyNC(CMe3)NCy]2Cl (4) and [Me3SiN(CMe3)NSiMe3]2InCl (5). Spectroscopic and elemental analyses confirm the formulas of all of these new species. Compound 4 is further characterized by X-ray crystallography and shown to possess a distorted trigonal bipyramidal coordination geometry around the metal center with the chloride group in the equatorial position. Crystal data for 4: triclinic, P1?, a = 12.545(7) ?, b = 13.482(8) ?, c = 11.965(6) ?, α = 102.08(5)°, β= 92.00(5)°, γ = 64.36(4)°, Z = 2, R = 0.029, Rw = 0.045.
