2-(2-Amino-4-nitrophenyl)-7-nitro-4H-3,1-benzoxazin-4-one
In the title compound, C14H8N4O6, the benzoxazin-4-one fused-ring system (r.m.s. deviation = 0.018 Å) is coplanar with the attached benzene ring [dihedral angle = 0.81 (4)°], there being an intra-molecular N-H⋯N hydrogen bond between them. Each nitro group is twisted out of the plane of the attached benzene ring [O-N-C-C torsion angles = 167.94 (11) and 170.38 (11)°]. In the crystal, amine-nitr...

The title mol-ecule, C(14)H(9)NO(2), is nearly planar with a dihedral angle of 3.72 (4)° beteewn the plane of the phenyl ring and the 3,1-benzoxazin-4-one fragment. The mol-ecules are arranged into stacks parallel to the b axis via π-π stacking inter-actions [centroid-centroid distance = 4.2789 (11) Å] and the crystal packing is additionally stabilized by weak inter-molecular C-H⋯O inter-actions.

The title co-crystal, 0.95C(20)H(20)O(3)·0.05C(20)H(19)ClO(3), arises as the chloride carried over during the synthesis shares a position with an aromatic H atom; the partial occupancies are 0.947 (2) and 0.053 (2) for H and Cl, respectively. The mol-ecular structure is stabilized by intra-molecular C-H⋯O contacts, forming pseudo five- and six-membered rings with S(5) and S(6) graph-set motifs,...
متن کامل(S)-6-Chloro-4-cyclopropylethynyl-4-trifluoromethyl-1H-3,1-benzoxazin-2(4H)-one
Two independent mol-ecules comprise the crystallographic asymmetric unit in the title anti-retroviral agent Efavirenz, C(14)H(9)ClF(3)NO(2), and these have noteworthy differences in conformation. The major difference relates to the orientation of the 2-cyclo-propyl-ethynyl residue relative to the six-membered heterocycle: this approaches an orthogonal disposition in mol-ecule a compared to a mo...
