4,5-Dichloro-2H-1,3-oxazine-2,6(3H)-dione
In the title compound, C(4)HCl(2)NO(3), the essentially planar (maximum deviation = 0.023 Å for the ring O atom) mol-ecules form N-H⋯O hydrogen bonds between mol-ecules lying about inversion centers, forming eight-membered rings with an R(2) (2)(8) motif in graph-set notation.

The mol-ecule of the title compound, C(12)H(14)Cl(2)O(2), lies about an inversion center. The six-membered ring is almost planar, with the largest deviation from the least-squares plane being 0.014 (4) Å. The mol-ecular conformation is stabilized by a weak intra-molecular C-H⋯O hydrogen bond. In the crystal, mol-ecules are packed into stacks along the c-axis direction, with an inter-centroid se...

The title compound, C(15)H(9)Cl(2)NO(3), crystallizes as an inversion twin, the ratio of the twin components being 0.43 (13):0.57 (13). The isoindoline group is planar and inclined by 77.63 (3)° to the aromatic ring substituent. The crystal structure is stabilized by aromatic π-π stacking inter-actions involving the benzene rings of adjacent isoindoline groups, with a centroid-centroid distance...

In the title compound, C(5)H(8)Cl(2)O(6)P(2), the two six-membered rings display chair conformations. The P=O bond distances are 1.444 (2) and 1.446 (2) Å. Weak inter-molecular C-H⋯O hydrogen bonds are present in the crystal structure.
متن کامل7,9-Dichloro-6H,12H-indolo[2,1-b]quinazoline-6,12-dione
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.
