Synthesis and characterization of the monomeric terphenyl metal halides Ge(Cl){C6H3-2,6-Trip(2)} (Trip = C6H2-2,4,6-i-Pr-3) and Sn(I){C6H3-2,6-Trip(2)} and the terphenyl metal amide Sn{N(SiMe3)(2)}{C6H3-2,6-Trip(2)}

The reaction of 1 equiv of (Et2O)LiC6H3-2,6-Trip(2) (Trip = C6H2-2,4,6-i-Pr -3) with either GeCl2-dioxane or SnI2 in ether affords the synthetically us eful monomeric aryl-metal halides Ge(Cl){C6H3-2,6-Trip(2)} (1) and Sn(I){C6 H3-2,6-Trip(2)} (2). The compounds have monomeric structures with two-coord ination and v-shaped geometries at the group 14 element in the solid state. Treatment of the amide Sn{N(SiMe3)(2)}(2) with (Et2O)LiC6H3-2,6-Trip(2) re sults in displacement of an amide group to afford the mixed aryl/amide spec ies Sn{N(SiMe3)(2)}{C6H3-2,6-Trip(2)) (3), which also has a monomeric v-sha ped geometry in the solid state.
