Bis(2-carboxy-anilinium) sulfate monohydrate.

ABSTRACT: In the title hydrated mol-ecular salt, 2C(7)H(8)NO(2) (+)·SO(4) (2-)·H(2)O, each cation in the asymmetric unit is stabilized by an intra-molecular N-H⋯O hydrogen bond. The O atoms of the sulfate ion are disordered over two sets of sites with an occupancy ratio of 0.541 (13):0.459 (13), which possibly optimizes the acceptance of N-H⋯O hydrogen bonds from the cations. The crystal structure also features aromatic π-π stacking [centroid-centroid separation = 3.842 (2) Å] and a C-H⋯π inter-action.

2-Carboxy-anilinium chloride monohydrate.

Project description:In the mol-ecule of the title compound, C(7)H(8)NO(2) (+)·Cl(-)·H(2)O, an intra-molecular N-H?O hydrogen bond results in the formation of a non-planar six-membered ring adopting a flattened boat conformation. In the crystal structure, inter-molecular O-H?O and N-H?Cl hydrogen bonds link the mol-ecules. There is a C=O?? contact between the carbonyl unit and the centroid of the benzene ring. There is a C=O?? contact [C?Cg = 3.5802?(18), C-O?Cg = 89?(1)°] between the carbonyl unit and the centroid of the benzene ring.

2-Carboxy-anilinium bromide monohydrate.

Project description:The title compound, C(7)H(8)NO(2) (+)·Br(-)·H(2)O, is isomorphous with 2-carboxy-anilinium chloride monohydrate and contains an intra-molecular N-H?O hydrogen bond, forming an S(6) motif. The main inter-molecular inter-actions are of the N-H?O/Br and O-H?O/Br types. Hydrogen-bonding dimers are formed via the carboxyl groups and the uncoordinated water mol-ecule, with centrosymmetric R(4) (4)(12) ring motifs, in tandem with centrosymmetric R(8) (4)(16) ring motifs formed by the cations and bromide anions. The hydrogen-bonded ring motifs inter-sect, forming chains with graph-set motif C(4) (3)(10) extending along the a axis. These form a two-dimensional hydrogen-bonded network in (101) which is extended along [010] through N-H?Br hydrogen bonds. Hydro-philic layers are generated at z = 0 and 1/2 which are sandwiched between alternate hydro-phobic layers across z = 1/4 and 3/4.

Bis[3-(dihydroxy-boryl)anilinium] sulfate.

Project description:In the title compound, 2C(6)H(9)BNO(2) (+)·SO(4) (2-), the dihydroxy-boryl group of one of the two independent boronic acid mol-ecules participates in (B)O-H?O(B) and N-H?O(B) hydrogen bonds, while the second is involved mainly in the formation of the charge-assisted heterodimeric synthon -B(OH)(2)?(-)O(2)SO(2) (-). These aggregates are further connected through N-H?O(sulfate) inter-actions, forming a complex three-dimensional hydrogen-bonded network.

Bifurcated hydrogen bonds are observed between perchlorate O atoms and adeninium cations.
