2-Phenyl-acetic acid-3-{(E)-2-[(E)-pyridin-3-yl-methyl-idene]hydrazin-1-ylidenemeth-yl}pyridine (2/1).

ABSTRACT: The asymmetric unit of the title 1:2 adduct, C(12)H(10)N(4)·2C(8)H(8)O(2), comprises a single mol-ecule of 2-phenyl-acetic acid and half a mol-ecule of 3-pyridine-aldazine; the latter is completed by crystallographic inversion symmetry. In the crystal, mol-ecules are connected into a three-component aggregate via O-H?N hydrogen bonds. As the carboxyl group lies above the plane through the benzene ring to which it is attached [C-C-C-C = 62.24?(17)°] and the 4-pyridine-aldazine mol-ecule is almost planar (r.m.s. deviation of the 16 non-H atoms = 0.027?Å), the overall shape of the aggregate is that of a flattened extended chair. Layers of these aggregates are connected by C-H?O and C-H?? inter-actions and stack parallel to (220).

In the crystal, mol-ecules are connected into a three-component aggregate via O-H⋯N hydrogen bonds.

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].

2-(4-Chloro-phen-yl)acetic acid-2-{(E)-[(E)-2-(2-pyridyl-methyl-idene)hydrazin-1-yl-idene]meth-yl}pyridine (1/1).

Project description:In the crystal of the title 1:1 adduct, C(8)H(7)ClO(2)·C(12)H(10)N(4), the components are linked by an O-H⋯N hydrogen bond between the carb-oxy-lic acid and one of the pyridine N atoms. In the acid, the carb-oxy-lic acid group is approximately normal to [dihedral angle = 72.9 (2)°] but twisted with respect to the plane through the benzene ring [C-C-C-O torsion angle = 25.4 (5)°]. The base is roughly planar [dihedral angle between rings = 12.66 (15)°; r.m.s. deviation of the 16 non-H atoms = 0.107 Å] and the conformations about both imine bonds are E. The dimeric aggregates are linked into a supra-molecular layer in the ab plane by C-H⋯O inter-actions.

(Z)-2-[2-(4-Methyl-benzyl-idene)hydrazin-yl]pyridine.

Project description:Mol-ecules of the title compound, C(13)H(13)N(3), are essentially planar (r.m.s. deviation for all non-H atoms = 0.054?Å). The dihedral angle between the two aromatic rings is 6.33?(5)°. In the crystal, pairs of centrosymmetrically related mol-ecules are linked through N-H?N hydrogen bonds, forming N-H?N dimers with graph-set motif R(2) (2)(8).

Bis{(Z)-[(E)-2-(pyridin-2-yl-methyl-idene)hydrazin-1-yl-idene][(pyridin-2-yl)methyl-sulfan-yl]methane-thiol-ato}nickel(II).

Project description:The title compound, [Ni(C13H11N4S2)2], was obtained by the reaction of S-2-picolyldi-thio-carbazate and pyridine-2-carbaldehyde with nickel(II) acetate. The Ni(II) atom is located on a twofold rotation axis and is bonded to four N atoms at distances of 2.037 (8) and 2.109 (9) Å, and to two S atoms at a distance of 2.406 (3) Å, leading to a distorted octa-hedral coordination. The angle between the mean planes of the coordinating moieties of the two symmetry-related tridentate ligands is 83.3 (2)°. In the crystal, complex mol-ecules are linked by weak C-H⋯S hydrogen bonds, π-π inter-actions between the pyridine rings [centroid-centroid distance = 3.775 (9) Å] and C-H⋯π inter-actions. The hydrogen-bonding inter-actions lead to the formation of layers parallel to (010); π-π inter-actions link these layers into a three-dimensional network.

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

Project description:The asymmetric unit of the title cocrystal, C(12)H(10)N(4)·2C(7)H(6)O(2), comprises a single mol-ecule of benzoic acid and one half-mol-ecule of 2-pyridine-aldazine situated about a centre of inversion. The carboxyl group is coplanar with the benzene ring to which it is connected [O-C-C-C = -172.47?(12)°] and similarly, the 2-pyridine-aldazine mol-ecule is planar (r.m.s. deviation of the 16 non-H atoms = 0.017?Å). In the crystal, mol-ecules are connected into a non-planar three-mol-ecule aggregate [dihedral angle between the benzene and pyridyl ring connected by the hydrogen bond = 61.30?(7)°] with a twisted Z-shape. Layers of 2-pyridine-aldazine mol-ecules in the ab plane are sandwiched by benzoic acid mol-ecules being connected by O-H?N and C-H?O inter-actions, the latter involving the carbonyl O atom so that each benzoic acid mol-ecule links three different 2-pyridine-aldazine mol-ecules. Inter-digitated layers stack along the c axis.

(E)-1-Phenyl-2-({5-[(1E)-(2-phenyl-hydrazin-1-yl-idene)meth-yl]-2-thien-yl}methyl-idene)hydrazine.

Project description:The title mol-ecule, C(18)H(16)N(4)S, adopts a U-shape with the aromatic groups lying syn and orientated in the same direction as the thio-phene S atom. The conformation about each of the C=N bonds is E. Overall, the mol-ecule is curved as seen in the dihedral angle of 30.26 (19)° formed between the terminal benzene rings. In the crystal, supra-molecular chains along the c axis are formed by a combination of N-H⋯N hydrogen bonds and N-H⋯π inter-actions.

(2E)-2-(2-Phenyl-hydrazin-1-yl-idene)propanoic acid.

Project description:The 13 non-H atoms comprising the title compound, C(9)H(10)N(2)O(2), are close to planar (r.m.s. deviation = 0.140?Å), with maximum deviations of 0.292?(1) and 0.210?(1)?Å to either side of the least-squares plane exhibited by the hy-droxy and carbonyl O atoms, respectively. The observed conformation is stabilized by an intra-molecular O-H?N hydrogen bond. The conformation about the N=C double bond [1.2909?(16)?Å] is E. The hy-droxy OH group also forms an inter-molecular hydrogen bond to a carbonyl O atom, and the amine H atom similarly forms an N-H?O hydrogen bond to a second carbonyl O atom. The result is the formation of a double layer with a flat topology. Layers stack along the a-axis direction connected by C-H?? inter-actions.

(E)-2-{4-[(Pyridin-2-yl)methyl-idene-amino]-phen-yl}acetic acid.

Project description:The title mol-ecule, C(14)H(12)N(2)O(2), forms a dimeric unit linked by a pair of symmetry-equivalent O-H?N hydrogen bonds. The aromatic rings are significantly twisted from each other with a dihedral angle of 44.04?(4)°.

2-{2-[(E)-(2-Benzoyl-hydrazin-1-yl-idene)meth-yl]phen-oxy}acetic acid.

Project description:In the title compound, C(16)H(14)N(2)O(4), the dihedral angle between the aromatic rings is 12.45 (6)°. The central C(=O)-N-N=C bridge is roughly planar (r.m.s. deviation = 0.0346 Å) and makes dihedral angles of 13.01 (7) and 0.56 (7)° with the attached phenyl and benzene rings, respectively. The acetic acid unit (r.m.s. deviation = 0.0066 Å) is twisted from its attached benzene ring [dihedral angle = 19.48 (6)°]. In the crystal, mol-ecules are linked by O-H⋯(O,N), N-H⋯O and C-H⋯O hydrogen bonds into sheets lying parallel to the bc plane. A weak aromatic π-π stacking inter-action is also observed [centroid-centroid distance = 3.7330 (7) Å].

Project description:The title Schiff base compound, C25H20N2, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit.

In the crystal, A and B dimers are linked by pairs of C-H?? inter-actions and further C-H?? bonds link the dimers into a three-dimensional network.
