Indium trichloride reacts with 3 equiv of lithium amide in diethyl ether to give In(NRR')(3) (R = Ph or t-Bu, R' = SiMe(3); R = t-Bu, R' = SiHMe(2)) and with 3 or 4 equiv of LiNMe(SiMe(3)) to yield Li[In{NMe(SiMe(3))}(4)]. The chloride also reacts with LiNPh(2) in THF to give the salt Li[In(NPh(2))(3)Cl] and with LiNRR' in pyridine to yield the neutral adduct In(NRR')(3)(py) (R = R' = Ph; R = Me, R' = SiMe(3)). The volatile liquids In[N(t-Bu)(SiHMe(2))](3) and In[NMe(SiMe(3))](3)(py) react with p-Me(2)Npy to form the solid compounds In[N(t-Bu)(SiHMe(2))](3)(p-Me(2)Npy) and In[NMe(SiMe(3))](3)(p-Me(2)Npy), respectively. X-ray crystallographic studies show that In(NPh(2))(3)(py), In[N(t-Bu)(SiHMe(2))](3)(p-Me(2)Npy), and the ether adduct of In[NPh(SiMe(3))](3) contain nearly planar In(amide)(3) fragments. Crystallographic studies also show that the anion in the salt [Li(THF)(4)][In(NPh(2))(3)Cl] is nearly tetrahedral and in [Li(p-Me(2)Npy)][In{NMe(SiMe(3))}(4)] the tetrahedral-like anion is bound to the Li cation via two amide nitrogens. The Li in the latter structure is also bonded to p-Me(2)Npy, resulting in a planar three-coordinate geometry for Li. Crystal data are the following.
