Bis(trichlorsilyl)phenylamine (1) and 2,2,4,4-tetrachlor-l,3-diphenyl-[l,3,2,4]diazadisiletid-ine (2) have been synthesized as potential precursors for the preparation of porous oxygen-free solids by the reaction of tetrachlorosilane with dilithiated aniline. Both compounds were characterized by crystal structure analysis. 1 crystallizes monoclinically, P2/n, a = 10.124(2), b = 12.701(2), c = 11.425(3) Å, β = 109.34(2)° and Z = 4 (R 1  = 4.6%, wR 2  = 11.6%, 1297 independent reflections). 2 crystallizes orthorhombically, Pbca, a = 11.42(1), b = 8.17(1), c = 17.05(1)Å, and Z = 4 (R 1  = 3.7%, wR 2  = 8.2%, 1923 independent reflections). Ammonolyses and polycondensation of 1 and 2 yield amorphous solids with low porosities.
