4-Nitro-phenol-piperazine (2/1).

ABSTRACT: In the title adduct, C6H5NO3·0.5C4H10N2, the piperazine ring possesses inversion symmetry and has a chair conformation. Its mean plane makes a dihedral angle of 65.45?(7)° with the 4-nitro-phenol ring. In the crystal, the piperazine ring is linked to two 4-nitro-phenol mol-ecules via O-H?N hydrogen bonds. The mol-ecules are also linked via bifurcated N-H?(O,O) hydrogen bonds involving the NO2 O atoms, forming a two-dimensional network lying parallel to (102). The networks are linked via C-H?O hydrogen bonds, forming a three-dimensional structure.

2-Amino-4-nitro-phenol monohydrate.

Project description:The title compound, C(6)H(6)N(2)O(3)·H(2)O, crystallizes with two formula units in the asymmetric unit. The mol-ecules are essentially planar with the nitro groups twisted slightly out of the ring planes [maximum deviations from the ring plane of 0.13?(2) and 0.22?(2)?Å in the two mol-ecules].

In the crystal structure, mol-ecules are linked by inter-molecular N-H?O, C-H?O, O-H?O and O-H?N inter-actions into a three-dimensional network.

l-Tryptophan 4-nitro-phenol tris-olvate.

Project description:The title compound, C(11)H(12)N(2)O(2)·3C(6)H(5)NO(3), comprises a zwitterionic amino acid formed by two nearly planar groups: (i) the indole ring and Cβ, and (ii) the carboxyl group, Cα, as well as the amine N atom, with r.m.s. deviations of 0.0084 and 0.0038 Å, respectively. The angle between these idealized planes is 39.47 (9)°. The amine group of the amino acid is in a syn (-sc) arrangement relative to the ring system. The overall crystal structure results from the packing of sheets parallel to the (001) planes. These sheets are formed by a pair of screw axis related parallel networks bound by hydrogen-bond and π-π stacking interactions. The intermolecular cohesion of all organic residues in each of the latter two-dimensional networks is achieved via strong hydrogen bonding, nitro-π and π-π stacking interactions.

2-Carboxyl-atopyridinium-4-nitro-phenol (1/1).

Project description:In the title 1:1 adduct, C6H5NO3·C6H5NO2, both mol-ecules are almost planar (r.m.s. deviations for the non-H atoms = 0.027 and 0.023 Å for 4-nitro-phenol and 2-carboxyl-atopyridinium, respectively). The pyridine mol-ecule crystallizes as a zwitterion (nominal proton transfer from the carb-oxy-lic acid group to the N atom in the ring). In the crystal, inversion dimers of the zwitterions linked by pairs of N-H⋯O hydrogen bonds generate R 2 (2)(10) loops; two 4-nitro-phenol mol-ecules link to the dimer by O-H⋯O hydrogen bonds, generating a four-molecule aggregate. These are linked by C-H⋯O inter-actions, forming a three-dimensional network.
