7,9-Dichloro-6H,12H-indolo[2,1-b]quinazoline-6,12-dione.

ABSTRACT: There are two independent mol-ecules in the asymmetric unit of the title compound, C(15)H(6)Cl(2)N(2)O(2). The conjugated four-ring system is essentially planar in each mol-ecule [maximum deviation = 0.089 (2) Å]. In the crystal, weak inter-molecular C-H⋯Cl, C-H⋯O and C-H⋯·N inter-actions help to stabilize the packing.
