4-Meth-oxy-benzamidinium nitrate.

ABSTRACT: The title salt, C8H11N2O(+)·NO3(-), was synthesized by a reaction between 4-meth-oxy-benzamidine (4-amidino-anisole) and nitric acid. The asymmetric unit comprises a non-planar 4-meth-oxy-benzamidinium cation and a nitrate anion. In the cation, the amidinium group has two similar C-N bond lengths [1.302 (3) and 1.313 (3) Å] and its plane forms a dihedral angle of 32.66 (5)° with the mean plane of the benzene ring. The nitrate-amidinium ion pair is not planar, as the dihedral angle between the planes defined by the CN2(+) and NO3(-) units is 19.28 (6)°. The ionic components are associated in the crystal via N-H⋯O hydrogen bonds, resulting in a three-dimensional network.

Benzamidinium 2-meth-oxy-benzoate.

Project description:The title mol-ecular salt, C7H9N2 (+.)C8H7O3 (-), was synthesized by reaction between benzamidine (benzene-carboximidamide) and 2-meth-oxy-benzoic acid. In the cation, the amidinium group has two similar C-N bonds [1.3070 (17) and 1.3145 (16) Å] and is almost coplanar with the benzene ring, making a dihedral angle of 5.34 (12)°. In the anion, the meth-oxy substituent forces the carboxyl-ate group to be twisted by 69.45 (6)° with respect to the plane of the aromatic fragment. In the crystal, the components are connected by two N(+)-H⋯O(-) (±)CAHB (charge-assisted hydrogen bonds), forming centrosymmetric ionic dimers with graph-set motif R 2 (2)(8). These ionic dimers are then joined in ribbons running along the b-axis direction by another R 4 (2)(8) motif involving the remaining N(+)-H⋯O(-) hydrogen bonds. Remarkably, at variance with the well known carb-oxy-lic dimer R 2 (2)(8) motif, the carboxyl-ate-amidinium pair is not planar, the dihedral angle between the planes defined by the CN2 (+) and CO2 (-) atoms being 18.57 (12)°.

4-Meth-oxy-benzamidinium 2,6-dimeth-oxy-benzoate.

Project description:The title compound, C(8)H(11)N(2)O(+)·C(9)H(9)O(4) (-), was synthesized by the reaction of 4-meth-oxy-benzamidine (4-amidino-anisole) and 2,6-dimeth-oxy-benzoic acid. The structure consists of non-planar pairs of hydrogen-bonded 4-meth-oxy-benzamidinium cations and 2,6-dimeth-oxy-benzoate anions. In the cation, the amidinium group is tilted by 27.94 (10)° with respect to the benzene ring. In the anion, the sterically bulky ortho-meth-oxy substituents force the carb-oxy-ate group to be twisted away from the plane of the benzene ring by 73.24 (6)°. The ions are further associated in the crystal into chains along the b-axis direction by inter-molecular N-H⋯O hydrogen bonds.

4-Meth-oxy-benzamidinium hydrogen oxalate monohydrate.

Project description:The title hydrated salt, C8H11N2O(+)·C2HO4(-)·H2O, was synthesized by a reaction of 4-meth-oxy-benzamidine (4-amidino-anisole) and oxalic acid in water solution. In the cation, the amidinium group forms a dihedral angle of 15.60 (6)° with the mean plane of the benzene ring. In the crystal, each amidinium unit is bound to three acetate anions and one water mol-ecule by six distinct N-H⋯O hydrogen bonds. The ion pairs of the asymmetric unit are joined by two N-H⋯O hydrogen bonds into ionic dimers in which the carbonyl O atom of the semi-oxalate anion acts as a bifurcated acceptor, thus generating an R(1)2(6) motif. These subunits are then joined through the remaining N-H⋯O hydrogen bonds to adjacent semi-oxalate anions into linear tetra-meric chains running approximately along the b axis. The structure is stabilized by N-H⋯O and O-H⋯O inter-molecular hydrogen bonds. The water mol-ecule plays an important role in the cohesion and the stability of the crystal structure being involved in three hydrogen bonds connecting two semi-oxalate anions as donor and a benzamidinium cation as acceptor.
