3-{[Bis(pyridin-2-ylmeth-yl)amino]-meth-yl}-2-hy-droxy-5-methyl-benz-aldehyde.

ABSTRACT: In the title compound, C(21)H(21)N(3)O(2), the pyridine rings and the benzene ring lie in a propeller arrangement around the central tertiary amine N atom. The dihedral angles formed by the benzene ring with the pyridine rings are 61.0?(3) and 49.6?(3)°, while the dihedral angle between the pyridine rings is 69.7?(3)°. The mol-ecular conformation is stabilized by intramolecular bifurcated O-H?N hydrogen bonds. In the crystal, inversion dimers are formed via pairs of C-H?N hydrogen bonds.

Crystal structure of 3-[({2-[bis-(2-hy-droxy-benz-yl)amino]-eth-yl}(2-hy-droxy-benz-yl)amino)-meth-yl]-2-hydroxy-5-methyl-benzaldehyde.

Project description:The non-symmetric title mol-ecule, C32H34N2O5, is based on a tetra-substituted ethyl-enedi-amine backbone. The mol-ecular structure consists of three hy-droxy-benzyl groups and one 2-hy-droxy-5-methyl-benzaldehyde group bonded to the N atoms of the di-amine unit. The ethyl-enedi-amine skeleton shows a regular extended conformation, while the spatial orientation of the phenol arms is governed by hydrogen bonds. In the 2-hy-droxy-5-methyl-benzaldehyde group, an intra-molecular S(6) O-H?O hydrogen bond is observed between the alcohol and aldehyde functions, and the neighbouring phenol arm participates in an intra-molecular S(6) O-H?N hydrogen bond. The third phenol group is involved in a bifurcated intra-molecular hydrogen bond with graph-set notation S(6) for O-H?N and O-H?O intra-molecular hydrogen bonds between neighbouring amine and phenol arms, respectively. Finally, the fourth phenol group acts as an acceptor in a bifurcated intra-molecular hydrogen bond and also acts as donor in an inter-molecular hydrogen bond, which connects inversion-related mol-ecules into dimers with R 4 (4)(8) ring motifs.

Project description:In the solvated title complex, [Ni(C(46)H(47)N(6)O(2))]ClO(4)·2CH(4)O, the coordination sphere around the Ni(II) ion can be described as distorted cis-NiO(2)N(4) octa-hedral defined by two phenolate O atoms and four N atoms from the hexa-dentate ligand. An intra-molecular bifurcated N-H?(N,O) hydrogen bond helps to establish the conformation of the complex mol-ecule. In the crystal, the components are connected by O-H?O and C-H?O hydrogen bonds.

Project description:In the title racemic compound, C(26)H(32)N(2)O(3), an intra-molecular O-H?N hydrogen bond is formed between the phenolic OH group and the tertiary amine N atom. Another O-H?N hydrogen bond that is formed between the OH group and the pyridine N atom links the mol-ecules into a polymeric chain extending along the a axis. The structure is further stabilized by intramolecular and intermolecular C-H?O interactions.

Bis{2,6-bis-[(2-hy-droxy-5-methyl-phen-yl)imino-meth-yl]pyridine} monohydrate.

Project description:The title compound, 2C(21)H(19)N(3)O(2)·H(2)O, was synthesized by a Schiff base condensation of 2,6-diformyl-pyridine with 2-amino-4-methyl-phenol in ethanol. In the crystal, two mol-ecules of 2,6-bis-[(2-hy-droxy-5-methyl-phen-yl)imino-meth-yl]pyridine dimer-ize via hydrogen bonding to a water mol-ecule, which lies on a twofold axis. There are also intra-molecular phenol-imine hydrogen bonds. The dimers are further linked via π-π (phen-yl-pyridine) [centroid-centroid distance = 3.707 (2) Å] and π-π edge-to-edge [3.392 (2) Å] inter-actions. The dihedral angles between the central ring and the two pendant rings are 11.46 (8) and 2.06 (8)° while the pendant rings make a dihedral angle of 10.14 (8)°.

Project description:The complete mol-ecule of the title compound, [Cd(C(6)H(12)NOS(2))(2)(C(12)H(10)N(4))(2)], is generated by crystallographic inversion symmetry. The distorted octa-hedral trans-N(2)S(4) donor set for the Cd(2+) ion is defined by two symmetrically S,S'-chelating dithio-carbamate anions and two pyridine N atoms derived from two monodentate 4-pyridine-aldazine (or 4-{[(pyridin-4-yl-methyl-idene)hydrazinyl-idene}meth-yl]pyridine) mol-ecules [dihedral angle between the aromatic rings = 17.33 (8)°]. In the crystal, mol-ecules are connected into a supra-molecular chain via O-H⋯N hydrogen bonds involving the 4-pyridine-aldazine N atoms not involved in coordination to cadmium. Weak C-H⋯O and C-H⋯N links consolidate the packing.
