2,2'-[1,1'-(Decane-1,10-diyldioxy-dinitrilo)diethyl-idyne]diphenol.

ABSTRACT: The salen-type bis-oxime title compound, C(26)H(36)N(2)O(4), lies about a crystallographic inversion centre. Classical intra-molecular O-H?N hydrogen bonds generate two S(6) ring motifs. In the crystal structure, pairs of weak inter-molecular C-H?O hydrogen bonds link adjacent mol-ecules into an infinite one-dimensional supra-molecular structure.

Project description:The title compound, C(19)H(22)N(2)O(4), was synthesized by the reaction of 2'-hydroxy-acetophenone with 1,3-bis-(amino-oxy)propane in ethanol. Intra-molecular O-H?N and weak C-H?O hydrogen bonds stabilize the three-dimensional structure. A twofold rotation axis passes through the molecule.

2,2'-[1,1'-(Hexane-1,6-diyldioxy-dinitrilo)diethyl-idyne]diphenol.

Project description:The molecule of the title compound, C(22)H(28)N(2)O(2), lies across an inversion centre with one half-mol-ecule in the asymmetric unit. The mol-ecule adopts an E configuration with respect to the azomethine C=N bond and the imino group is coplanar with the aromatic ring. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the hexa-methyl-ene bridge. There are intra-molecular O-H?N hydrogen bonds between the hydroxyl groups and the oxime N atoms. There are also weak inter-molecular C-H?O bonds that link each mol-ecule to two others, forming chains along the a axis.

2,2'-[1,1'-(Octane-1,8-diyldioxy-dinitrilo)diethyl-idyne]diphenol.

Project description:The title compound, C(24)H(32)N(2)O(4), has a crystallographic inversion centre at the mid-point of the central C-C bond. At each end of the mol-ecule, intra-molecular O-H?N hydrogen bonds generate six-membered S(6) ring motifs. The crystal structure is stabilized by pairs of weak inter-molecular C-H?O hydrogen bonds that link neighbouring mol-ecules into R(2) (2)(40) ring motifs, which in turn form infinite one-dimensional supra-molecular ribbon structures.

2,2'-[1,1'-(Propane-1,3-diyldioxy-dinitrilo)diethyl-idyne]di-1-naphthol.

Project description:The mol-ecule of the title compound, C(27)H(26)N(2)O(4), lies across a crystallographic inversion centre and adopts an l-shaped configuration. Within the mol-ecule, the two naphthalene units are approximately perpendicular, making a dihedral angle of 80.24?(5)°. The two intramolecular O-H?N hydrogen bonds, generate S(6) ring motifs. In the crystal structure, every mol-ecule links five other mol-ecules into an infinite cross-linked layered supra-molecular structure via inter-molecular C-H?O hydrogen bonds, C-H?? inter-actions and ?-? stacking inter-actions [centroid-centroid distance = 3.956?(4)?Å].

Project description:The mol-ecule of the title compound, C(31)H(34)N(2)O(4), adopts an L-shaped configuration, in which the naphthalene units are approximately perpendicular, making a dihedral angle of 87.89?(3)°.

5,5'-Bis(diethyl-amino)-2,2'-[butane-1,4-diyldioxy-bis(nitrilo-methyl-idyne)]-diphenol.

Project description:The title complex, C(26)H(38)N(4)O(4), was synthesized by the reaction of 4-diethyl-amino-2-hydroxy-benzaldehyde with 1,4-bis-(amino-oxy)butane in ethanol. It crystallizes as discrete centrosymmetric molecules adopting an extended conformation where the two salicylaldoxime groups are separated from each other. Intra-molecular O-H⋯N hydrogen bonding is observed between the hydr-oxy groups and oxime N atoms. Inter-molecular π-π stacking inter-actions [3.979 (2) Å] between aromatic rings are apparent in the crystal structure. Each ethyl group is disordered over two positions; in one the site occupancy factors are 0.55 and 0.45, in the other 0.53 and 0.47.

Project description:The title Schiff base, C(21)H(26)N(2)O(2), contains two intra-molecular O-H?N hydrogen bonds between the hydroxyl groups and the nearest imine N atoms, each leading to a six-membered ring. Weak C-H?O hydrogen bonds result in a ladder network running along the a axis. In addition, inter-molecular C-H?? inter-actions serve to stabilize the extended structure.

Project description:In the title complex, [Ni(C(26)H(22)N(2)O(4))], the Ni(II) atom has a slight distortion toward tetra-hedral geometry from a square-planar structure, coordinated by two O and two N atoms of the tetra-dentate salen-type bis-oxime 2,2'-[1,1'-(ethyl-enedioxy-dinitrilo)diethyl-idyne]di-1-naphtholate (L(2-)) unit, with a mean deviation of 0.022?Å from the N(2)O(2) plane. The N- and O-donor atoms are mutually cis. The dihedral angle between two naphthalene systems of the L(2-) ligand is 67.59?(4)°. The crystal structure is stabilized by inter-molecular C-H?O and C-H?? inter-actions, which link neighbouring mol-ecules into extended chains along the b axis.
