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

ABSTRACT: 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.

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. ...[more]

Project description: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'-[(E,E)-1,1'-(2,2-Dimethyl-propane-1,3-diyldinitrilo)diethyl-idyne]diphenol.

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:The complete mol-ecule of the title compound, C(22)H(28)N(2)O(4), is generated by a crystallographic inversion centre at the mid-point of the central C-C bond. The two benzene rings are parallel to each other with a perpendicular inter-planar spacing of 1.488?(2)?Å. Intra-molecular O-H?N hydrogen bonds generate two six-membered rings with S(6) motifs. In the crystal, weak inter-molecular C-H?O hydrogen bonds link neighbouring mol-ecules into an infinite three-dimensional network, which is further stabilized by weak C-H?? inter-actions.

2,2'-{1,1'-[Pentane-1,5-diyl-bis(oxy-nitrilo)]-diethyl-idyne}diphenol.

Project description:In the title compound, C(21)H(26)N(2)O(4), there is half a mol-ecule in the asymmetric unit with a crystallographic twofold rotation axis passing through the central C atom of the -CH=N-O-(CH(2))(5)-O-N=CH- bridge. The dihedral angle formed by the two benzene rings is 80.85?(2)°. Strong intra-molecular O-H?N and C-H?O hydrogen bonds help to establish the molecular conformation. There are also weak inter-molecular ?-? stacking inter-actions between neighbouring benzene rings [centroid-centroid separation = 3.502?(3)?Å].

Project description:The title Schiff base compound, C(23)H(30)N(2)O(2), has crystallographic twofold rotation symmetry. An intra-molecular O-H?N hydrogen bond forms a six-membered ring, producing an S(6) ring motif. The imino group is coplanar with the benzene ring.
