2-Amino-benzoic acid-4-(pyridin-4-yl-disulfan-yl)pyridine (1/1).

ABSTRACT: The title 1:1 co-crystal, C(7)H(7)NO(2)·C(10)H(8)N(2)S(2), features a highly twisted 4-(pyridin-4-yldisulfan-yl)pyridine mol-ecule [dihedral angle between the pyridine rings = 89.06?(10)°]. A small twist is evident in the 2-amino-benzoic acid mol-ecule, with the C-C-C-O torsion angle being -7.7?(3)°. An N-H?O hydrogen bond occurs in the 2-amino-benzoic acid mol-ecule. In the crystal, mol-ecules are linked by O-H?N and N-H?N hydrogen bonds into a supra-molecular chain along the b axis. These are connected into layers by ?-? inter-actions occurring between pyridine rings [centroid-centroid distance = 3.8489?(15)?Å]. The layers are connected along the a axis by C-H?O contacts. The crystal studied was a racemic twin.

The title 1:1 co-crystal, C(7)H(7)NO(2)·C(10)H(8)N(2)S(2), features a highly twisted 4-(pyridin-4-yldisulfan-yl)pyridine mol-ecule [dihedral angle between the pyridine rings = 89.06 (10)°]. A small twist is evident in the 2-amino-benzoic acid mol-ecule, with the C-C-C-O torsion angle being -7.7 (3)°. An N-H⋯O hydrogen bond occurs in the 2-amino-benzoic acid mol-ecule.

2-Amino-benzoic acid-4-[2-(pyridin-4-yl)eth-yl]pyridine (2/1).

Project description:The asymmetric unit of the title co-crystal, C12H12N2·2C7H7NO2, comprises a centrosymmetric 4-[2-(pyridin-4-yl)eth-yl]pyridine mol-ecule and a 2-amino-benzoic acid mol-ecule in a general position. The acid has a small twist between the carb-oxy-lic acid residue and the ring [dihedral angle = 7.13?(6)°] despite the presence of an intra-molecular N-H?O(carbon-yl) hydrogen bond. Three-mol-ecule aggregates are formed via O-H?N(pyrid-yl) hydrogen bonds, and these are connected into supra-molecular layers in the bc plane by N-H?O(carbon-yl) hydrogen bonds and ?-? inter-actions between pyridine and benzene rings [inter-centroid distance = 3.6332?(9)?Å]. Layers are connected along the a axis by weak ?-? inter-actions between benzene rings [3.9577?(10)?Å].

Project description:The title mol-ecule, C(14)H(12)N(2)O(2), exhibits a V-shaped conformation with a dihedral angle of 59.69 (3)° between the benzene and pyridine rings. In the crystal, O-H⋯N hydrogen bonds link the mol-ecules into zigzag chains along [010].

Benzoic acid-4-{(1E)-[(E)-2-(pyridin-4-yl-methyl-idene)hydrazin-1-yl-idene]meth-yl}pyridine (2/1).

Project description:In the title co-crystal, C(12)H(10)N(4)·2C(7)H(6)O(2), the complete 4-pyridine-aldazine mol-ecule is generated by a crystallographic centre of inversion. In the crystal, mol-ecules are connected into a three component aggregate via O-H?N hydrogen bonds. As both the benzoic acid [O-C-C-C torsion angle = 174.8?(2)°] and 4-pyridine-aldazine (r.m.s. deviation of the 16 non-H atoms = 0.041?Å) mol-ecules are almost planar, the resulting three-component aggregate is essentially planar. The crystal packing comprises layers of the three-component aggregates of alternating orientation stacked along the b axis; the connections between the mol-ecules are of the types C-H?? and ?-? [pyridine-benzene centroid-centroid distance = 3.787?(4)?Å].

Project description:In the title 2:1 adduct, C(14)H(10)O(4)S(2)·0.5C(10)H(8)N(2)O(2), which arose from an unexpected oxidation of a precursor, the dihedral angle between the aromatic rings in the disulfide is 82.51?(11)°.

2-[2,6-Bis(pyrazin-2-yl)pyridin-4-yl]benzoic acid.

Project description:In the title compound, C20H13N5O2, the two pyrazine rings are nearly coplanar with the central pyridine ring, forming dihedral angles of 2.21?(9) and 4.57?(9)°. In contrast, the strong steric hindrance caused by the ortho-carboxyl group on the phenyl ring makes this ring rotate out of the attached pyridine ring plane by 52.60?(9)°. The carboxyl group is twisted from the phenyl ring by 22.6?(1)°. In the crystal, aromatic ?-? stacking inter-actions [centroid-centroid distances = 3.9186?(4) and 3.9794?(5)?Å] occur between the anti-parallel mol-ecules, generating infinite chains along [100]. O-H?O hydrogen bonds connect the chains, leading to the formation of a two-dimensional supra-molecular network parallel to (010). Inter-molecular C-H?N hydrogen bonds are also observed.

3,5-Bis[(pyridin-4-yl)meth-oxy]benzoic acid.

Project description:Single crystals of the title compound, C19H16N2O4, were obtained under hydro-thermal conditions by an unintended recrystallization of the employed microcrystalline starting material. The [(pyridin-4-yl)meth-oxy]benzoic acid unit is nearly planar, with a maximum deviation from the least-squares plane of 0.194?(2)?Å. This plane is inclined by 35.82?(6)° to that defined by the second (pyridin-4-yl)meth-oxy group [in which the largest deviation from the least-squares plane is 0.013?(2)?Å]. In the crystal, mol-ecules are linked by O-H?N hydrogen bonds involving the acid hy-droxy group and a pyridine N atom into chains parallel to [-201].

2-Amino-5-bromo-pyridine-benzoic acid (1/1).

Project description:In the title adduct, C(5)H(5)BrN(2)·C(7)H(6)O(2), the carboxyl group of the benzoic acid mol-ecule is twisted away from the attached ring by 12.97?(11)°. The 2-amino-5-bromo-pyridine mol-ecules inter-act with the carboxylic group of neighbouring benzoic acid mol-ecules through N-H?O and O-H?N hydrogen bonds, forming cyclic R(2) (2)(8) hydrogen-bonded motifs and linking the mol-ecules into a two-dimensional network lying parallel to (100). The crystal structure is further stabilized by weak C-H?O hydrogen bonds.

2-Amino-5-chloro-pyridine-benzoic acid (1/1).

Project description:In the title compound, C(5)H(5)ClN(2)·C(7)H(6)O(2), the carboxyl group of the benzoic acid mol-ecule is twisted away from the attached ring by 14.22?(7)°. In the crystal, the 2-amino-5-chloro-pyridine mol-ecules inter-act with the carboxyl groups of benzoic acid mol-ecules through N-H?O and O-H?N hydrogen bonds, forming cyclic R(2) (2)(8) hydrogen-bonded motifs, and linking the mol-ecules into chains parallel to the [001] direction. Neighbouring 2-amino-5-chloro-pyridine mol-ecules are also centrosymmetrically paired through C-H?Cl hydrogen bonds, forming another R(2) (2)(8) motif. The crystal structure is further stabilized by weak C-H?O hydrogen bonds.

Benzoic acid-3,4-bis-[(pyridin-3-ylmeth-yl)amino]-cyclo-but-3-ene-1,2-dione (1/2).

Project description:In the title co-crystal, C(16)H(14)N(4)O(2)·2C(7)H(6)O(2), the 3,4-bis-[(pyridin-3-ylmeth-yl)amino]-cyclo-but-3-ene-1,2-dione squareamide mol-ecules assemble into chains along the b axis via N-H?O hydrogen bonds. The benzoic acid mol-ecules then hydrogen bond to the pyridine rings via O-H?N hydrogen bonds, supported by weaker C-H?O hydrogen bonds, forming extended ribbons. The asymmetric unit consists of a half squareamide mol-ecule, sitting on a special position around a twofold axis, and one benzoic acid mol-ecule on a general position.

2-{4-[Acet-yl(eth-yl)amino]-benzene-sulfonamido}-benzoic acid.

Project description:In the title compound, C(17)H(18)N(2)O(5)S, the dihedral angle between the aromatic rings is 68.59?(10)° and the C-S-N-C torsion angle is -81.84?(18)°. The mol-ecular conformation is stabilized by an intra-molecular N-H?O hydrogen bond, generating an S(6) ring. In the crystal, mol-ecules are linked by C-H?O and O-H?O hydrogen bonds into a three-dimensional network.
