2-Carb-oxy-1-(3-nitro-phen-yl)ethanaminium perchlorate.

ABSTRACT: In the title compound, C(9)H(11)N(2)O(4) (+)·ClO(4) (-), the organic cations form centrosymmetric dimers via a pair of O-H?O hydrogen bonds between the carboxyl groups. In the crystal, N-H?O inter-actions between the protonated amine group and the perchlorate anions and the nitro group connect the components into a two-dimensional network parallel to (001).

2-Carb-oxy-1-(3-nitro-phen-yl)ethanaminium perchlorate.

Project description:In the cation of the title compound, C(9)H(11)N(2)O(4) (+)·ClO(4) (-), the conformation is stabilized by an intra-molecular N-H?O hydrogen bond. In the crystal packing, centrosymmetrically related cations inter-act through inter-molecular O-H?O hydrogen bonds involving the carb-oxy groups, forming dimers. The dimers and the perchlorate anions are further linked into layers parallel to the ab plane by C-H?O and N-H?O hydrogen-bonding inter-actions.

N-[4-(4-Nitro-phen-oxy)phen-yl]acetamide.

Project description:The asymmetric unit of the title compound, C(14)H(12)N(2)O(4), contains two mol-ecules that differ principally in the orientation of the acetamide substituent to the adjacent benzene ring with dihedral angles of 44.77 (7) and 19.06 (7)°. The dihedral angles between the benzene rings are 64.46 (4) and 80.84 (4)°. In the crystal, classical N-H⋯O hydrogen bonds form C(4) chains along [100]. These chains are inter-linked by C-H⋯O contacts forming R(2) (2)(10) rings. In the crystal, π-π inter-actions are observed with a distance of 3.5976 (18) Å between the centroids of the nitro-substituted benzene rings of one type of mol-ecule.

Syntheses and crystal structures of 4-(4-nitro-phen-yl)piperazin-1-ium benzoate monohydrate and 4-(4-nitro-phen-yl)piperazin-1-ium 2-carb-oxy-4,6-di-nitro-phenolate.

Project description:Crystal structures are reported for two mol-ecular salts containing the 4-(4-nitro-phen-yl)piperazin-1-ium cation. Co-crystallization from methanol/ethyl acetate solution of N-(4-nitro-phen-yl)piperazine with benzoic acid gives the benzoate salt, which crystallizes as a monohydrate, C10H14N3O2·C7H5O2·H2O, (I), and similar co-crystallization with 3,5-di-nitro-salicylic acid yields the 2-carb-oxy-4,6-di-nitro-phenolate salt, C10H14N3O2·C7H3N2O7, (II). In the structure of (I), a combination of O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds links the components into sheets, while in the structure of (II), the supra-molecular assembly, generated by hydrogen bonds of the same types as in (I), is three dimensional. Comparisons are made with the structures of some related compounds.
