3-Carboxy-anilinium hemioxalate.

ABSTRACT: In the title compound, C(7)H(8)NO(2) (+)·0.5C(2)O(4) (2-), the asymmetric unit consists of an 3-carboxy-anilinium cation, and one-half of an oxalate anion, which lies on a twofold rotation axis. The crystal packing is consolidated by inter-molecular N-H?O and O-H?O hydrogen bonds. The structure is built from infinite chains of cations and oxalate anions extending parallel to the b and c axes. The crystal studied was a non-merohedral twin. The ratio of the twin components refined to 0.335?(3):0.665?(3).

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.

Bis(2-carboxy-anilinium) sulfate monohydrate.

Project description: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 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.

4-(Carboxy-meth-oxy)anilinium bromide.

Project description:In the title hydro-bromide salt, C(8)H(10)NO(3) (+)·Br(-), the positive charge resides on the N atom and the carboxyl -CO(2) end of the cation carries an H atom. In the crystal, N-H?Br, O-H?Br and N-H?O hydrogen bonds link the cations and anions, forming a ladder propagating along the a axis.

4-(Carboxy-meth-yl)anilinium chloride.

Project description:In the crystal of the title compound, C(8)H(10)NO(2) (+)·Cl(-), alternating layers of hydro-phobic and hydro-philic zones stack along the c axis. The chloride anions are sandwiched between the 4-(carboxy-meth-yl)anilinium layers, forming inter-molecular O-H?Cl and N-H?Cl hydrogen bonds with the ammonium and carboxyl groups of the cations. In addition, inter-molecular N-H?O and weak C-H?O and C-H?Cl hydrogen bonds help stabilize the crystal structure.

Hydrogen bonding in 2-carboxy-anilinium dihydrogen phosphite at 100?K.

Project description:The title compound, C(7)H(8)NO(2) (+)·H(2)PO(3) (-), is formed from alternating layers of organic cations and inorganic anions stacked along the a-axis direction. They are associated via O-H?O, N-H?O and C-H?O hydrogen bonding, giving rise to two different R(2) (2)(8) graph-set motifs and generating a three-dimensional network.

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