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

ABSTRACT: 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.

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)°].

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.

(1Z,2E)-N'-{2-Chloro-1-methyl-2-[2-(4-methyl-phen-yl)hydrazin-1-yl-idene]ethyl-idene}-4-meth-oxy-benzohydrazide.

Project description:The asymmetric unit of the title compound, C(18)H(19)ClN(4)O(2), contains two mol-ecules, in which the dihedral angles between the benzene rings are 43.60 (12) and 58.65 (13)°. The hydrazine N atoms are twisted slightly out of the planes of the tolyl and meth-oxy-benzene rings: the C-C-N-N and N-N-C-C torsion angles are 171.1 (2) and -174.4 (2)°, respectively, for one mol-ecule and -177.4 (2) and -170.6 (2)°, respectively, for the other. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds into chains propagating along the b-axis direction.

Project description:The complete mol-ecule of the title hydrazine carbodi-thio-ate derivative, C32H30N4O2S4, is generated by a crystallographic twofold axis that bis-ects the di-sulfide bond. The mol-ecule is twisted about this bond with the C-S-S-C torsion angle of 90.70?(8)° indicating an orthogonal relationship between the symmetry-related halves of the mol-ecule. The conformation about the imine bond [1.282?(2)?Å] is E and there is limited delocalization of ?-electron density over the CN2C residue as there is a twist about the N-N bond [C-N-N-C torsion angle = -166.57?(15)°]. An intra-molecular hydroxyl-O-H?N(imine) hydrogen bond closes an S(6) loop. In the crystal, methyl-ene-C-H??(tol-yl) contacts assemble mol-ecules into a supra-molecular layer propagating in the ab plane: the layers stack without directional inter-actions between them. The analysis of the calculated Hirshfeld surfaces confirm the importance of H?H contacts, which contribute 46.7% of all contacts followed by H?C/C?H contacts [25.5%] reflecting, in part, the C-H??(tol-yl) contacts. The calculation of the inter-action energies confirm the importance of the dispersion term and the influence of the stabilizing H?H contacts in the inter-layer region.

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 ?-? stacking inter-action is also observed [centroid-centroid distance = 3.7330?(7)?Å].

Project description:The title compound, [Ir(?(5)-C5Me5)Cl(C18H14ClN3)]B(C6H5)4, is chiral at the metal center and crystallizes as a racemate. In the cation, the hydrazinyl-idene-pyridine ligand is N,N-coordinated through the N-pyridyl and N-hydrazinyl-idene groups forming a five-membered metallacycle. An intra-molecular C-H?Cl hydrogen bond is observed. In the crystal, centrosymmetrically-related cations are connected by C-Cl?? inter-actions, forming a dimeric structure. The crystal packing is further stabilized by weak inter-ionic C-H?? inter-actions.

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].

Ethyl 2-chloro-[2-(4-chloro-phen-yl)hydrazin-1-yl-idene]acetate.

Project description:The title compound, C(10)H(10)Cl(2)N(2)O(2), features a planar C(ar)-N(H)-N=C(Cl) unit [torsion angle = 5.5 (4)°] whose benzene substituent is coplanar with it [dihedral angle = 4.7 (4)°]; this unit is slightly twisted with respect to the carboxyl -CO(2) fragment [dihedral angle = 2.2 (52)°]. The amino group acts as a hydrogen-bond donor to the carbonyl O atom of an adjacent mol-ecule; the hydrogen bond generates a helical polymer that runs along the b axis of the monoclinic unit cell.
