چکیده
2-Phenoxybenzenesulfonamide, C(12)H(11)NO(3)S, (I), crystallizes in space group P-1 with Z' = 4, but the structure closely mimics the monoclinic space group P2(1)/b with Z' = 2. The molecules of (I) are linked by a combination of N-H...O and C-H...O hydrogen bonds into two independent chains of centrosymmetric edge-fused R(2)(2)(18) and R(6)(6)(34) rings. N-Methyl-2-phenoxybenzenesulfonamide, C(13)H(13)NO(3)S, (II), crystallizes in space group P2(1) with Z' = 1, and is an example of spontaneous resolution. The molecules are linked by N-H...O and C-H...O hydrogen bonds into chains of spiro-fused R(2)(2)(12) rings, and these chains are linked into sheets by a single C-H...pi(arene) hydrogen bond.

The title compound, C(14)H(12)N(4)O(6)·C(3)H(7)NO, is a monoclinic polymorph of an already published structure [Baughman et al. (2004 ▶). Acta Cryst. C60, 103-106]. In the previously reported structure, the compound crystallized in the triclinic space group P[Formula: see text] (Z = 2), whereas the structure reported here is monoclinic (P2(1)/n, Z = 4). In both forms, two intra-molecular hydrog...

The title compound, C(7)H(8)N(2)O(2), is monoclinic (space group P2(1)/n) at 295 (2) K with Z' = 2. The two types of molecule form independent C(7) chains, and the structure is related to that of the low-temperature triclinic polymorph, where Z' = 4 in P1, by a simple displacive transformation.

The title compound, C17H15N3O2, is a monoclinic polymorph (P21/c with Z' = 1) of the previously reported triclinic (P-1 with Z' = 2) form [Gajera et al. (2013 ▸). Acta Cryst. E69, o736-o737]. The mol-ecule in the monoclinic polymorph features a central pyrazolyl ring with an N-bound p-tolyl group and a C-bound 1,3-benzodioxolyl fused-ring system on either side of the C atom bearing the amino gr...
