Project description:In the title compound, C(7)H(10)N(+)·NO(3) (-), the 3-methyl-anilinium cations inter-act with the nitrate anions through strong bifurcated N(+)-H?(O,O) hydrogen bonds, forming a two-dimensional hydrogen-bonded network.

Project description:The asymmetric unit of the title compound, C(7)H(10)N(+)·NO(3) (-), consists of a 4-methyl-anilinium cation protonated at the amino group and a nitrate anion. In the crystal, anions and cations are linked through N-H?O and N-H?(O,O) hydrogen bonds, buiding a corrugated layer structure parallel to (001).

Project description:In the title salt, C(8)H(12)N(+)·NO(3) (-), all non-H atoms of the cation lie on mirror planes. The nitrate counteranion has m symmetry and acts as a hydrogen-bond acceptor of N-H?O hydrogen bonds, connecting the cations and anions into layers running parallel to the ab plane.

Project description:In the title compound, C(7)H(7)N(2) (+)·NO(3) (-), all atoms of the cation, with the exception of two H atoms of the NH(3) group, lie on a mirror plane, while the anion lies across this plane with the N and one O atom on the mirror plane. In the crystal structure, the organic cations and NO(3) (-) anions are linked by N-H?N and N-H?O hydrogen bonds, forming a two-dimensional network parallel to (100).

Project description:In the title compound, C(6)H(7)IN(+)·NO(3) (-), ?-? stacking inter-actions [centroid-centroid distances = 4.014?(4) and 4.029?(4)?Å] stabilize the crystal structure and strong N-H?O and N-H?N hydrogen bonds link the cations and anions into zigzag chains running parallel to the c axis. The asymmetric unit contains two unique cations and anions.

Project description:The title compound, C(7)H(10)NO(+)·NO(3) (-), crystallized with two p-ansidinium cations and two nitrate anions in the asymmetric unit. As well as Columbic and van der Waals forces, moleucles inter-act via multiple bifurcated N-H?O hydrogen bonds that help consolidate the crystal packing, resulting in a three-dimensional network.

Project description:The title salt, C(7)H(9)ClNO(+)·NO(3) (-), exhibits extensive hydrogen bonding between the ammonium functional group and the nitrate anion. A two-dimensional network of bifurcated N-H?O hydrogen bonds generates corrugated layers in the bc plane. The organic mol-ecules are stacked in a parallel orientation as a result of ?-? inter-actions, with an inter-ring distance of 3.837?Å.

Project description:In the cation of the title compound, C(7)H(7)N(2) (+)·NO(3) (-), the nitrile group and the benzene ring are almost coplanar (r.m.s. deviation = 0.006?Å). In the crystal, the ions are connected by bifurcated N-H?(O,O) hydrogen bonds, forming a two-dimensional network parallel to (001).

Project description:The title compound, C7H8NO2(+)·NO3(-)·C7H7NO2, exists in the form of a protonated dimer of two anilinium-3-carboxyl-ate mol-ecules related by an inversion center, and a nitrate anion located on a twofold rotation axis. The bridging H atom occupies, with equal probability, the two sites associated with the carboxyl atoms. In addition to the strong O-H?O hydrogen bond, in the crystal, the various units are linked via N-H?O and C-H?O hydrogen bonds forming a three-dimensional structure.

Project description:In the title hydrated salt, C(8)H(11)N(2)O(+)·NO(3) (-)·H(2)O, the N-C bond distances [1.349?(2) and 1.413?(2)?Å] along with the sum of the angles (359.88°) around the acetamide N atom clearly indicate that the heteroatom has an sp(2) character. The ammonium group is involved in a total of three N-H?O hydrogen bonds, two of these are with a water mol-ecule, which forms two O-H?O hydrogen bonds. All these hydrogen bonds link the ionic units and the water mol-ecule into infinite planar layers parallel to (100). The remaining two N-H?O inter-actions in which the ammoniun group is involved link these layers into an infinite three-dimensional network.
