چکیده
Molecules of the title compound [systematic name: 5-nitro-1H-isoindole-1,3(2H)-dione], C14H8N2O4, adopt a conformation in the solid state which renders them chiral, and they are linked by three distinct types of direction-specific intermolecular interaction. The molecules are linked by two C-H...O hydrogen bonds [H...O = 2.50 and 2.52 A, C...O = 3.118 (7) and 3.294 (7) A, and C-H...O = 123 and 139 degrees ] into chains of edge-fused R(3)(3) (12) rings, which are themselves weakly linked into sheets by a combination of an aromatic pi-pi stacking interaction and a sheared-parallel carbonyl-carbonyl interaction.

In the mol-ecule of the title compound, C(20)H(11)ClN(2)O(3), the pyran ring adopts a flattened-boat conformation. In the crystal structure, inter-molecular N-H⋯N and N-H⋯O hydrogen bonds generate edge-fused R(2) (2)(12) and R(2) (2)(14) ring motifs; the hydrogen-bonded motifs are linked to each other, forming a three-dimensional network. A π-π contact [centroid-to-centroid distance = 3.879 (3)...

In the title thio-semicarbazone derivative, C(9)H(10)N(4)OS·H(2)O, intra-molecular N-H⋯N hydrogen bonds result in the formation of two nearly coplanar five- and six-membered rings, which are also almost coplanar with the adjacent phenyl ring. The oxime group has an E configuration and is involved in inter-molecular O-H⋯O hydrogen bonding as a donor. In the crystal structure, intra-molecular O-H...

In the title compound, C13H9N3O5, the mean plane of the non-H atoms of the central amide fragment C-N-C(=O)-C [r.m.s. deviation = 0.0442 Å] forms dihedral angles of 71.76 (6) and 24.29 (10)° with the C-bonded and N-bonded benzene rings, respectively. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds forming C(4) chains along [100]. Weak C-H⋯O contacts link the mol-ecules into (100) ...
