Abstract
Accurate molecular parameters for the tricyclic system in the compound ethyl 3-(4-chlorobenzoyl)pyrrolo[1,2-c]-quinazoline-1-carboxylate have been determined by X-ray analysis. The compound crystallizes in the triclinic system, space group P1 with a = 8.1761(4)Å, b = 9.2255(4)Å, c = 11.5258(4)Å, α = 92.014(3)°, β = 90.871(3)°, γ = 99.323(2)°, V = 857.17(6)Å3 and Z = 2. The crystal structure was solved by direct methods and refined by full-matrix least-squares on F2 to final values of R1 = 0.0375 and wR2 = 0.0917.
