The crystal and molecular structure of 1‐Ethyl‐3[tris(trimethylsiloxyl)silyl]pyrrolinium hydro‐chloride (C 15 H 38 N + O 3 Si 4 · C 1− ) has been determined by direct methods. The title compound crystallizes in the monoclinic space group C2/c with a = 20.640(3), b = 19.494(2), c = 27.34(3) Å, β = 90.60(4)°, V = 11000(13) Å 3 , Z = 16, D x = 1.034 Mg m −3 . There are two molecules with different conformations in the crystal. The pyrroline rings are non‐planar.‐The SiOSi angles range from 149(1)° to 163(1)°. Two of the SiMe 3 groups are disordered. All molecules are connected by C 1− – N + contacts and C 1− ‐ HN + hydrogen bonds to form double chains.
