Crystal structure of 1,3-bis-[(E)-4-meth-oxy-benzyl-idene-amino]-propan-2-ol.

ABSTRACT: The title Schiff base, C₁₉H₂₂N₂O₃, was synthesized via the condensation reaction of 1,3-di-amino-propan-2-ol with 4-meth-oxy-benzaldehyde using water as solvent. The mol-ecule exists in an E,E conformation with respect to the C=N imine bonds and the dihedral angle between the aromatic rings is 37.25?(15)°. In the crystal, O-H?N hydrogen bonds link the mol-ecules into infinite C(5) chains propagating along the a-axis direction. The packing of these chains is consolidated by C-H?O inter-actions and C-H?? short contacts, forming a three-dimensional network.

Crystal structure of 1,3-bis-[(E)-benzyl-idene-amino]-propan-2-ol.

Project description:In the title compound, C17H18N2O, the central carbon atom with the OH substituent and one of the (E)-benzyl-idene-amino substituents are disordered over two sets of sites with occupancies of 0.851 (4) and 0.149 (4). The relative positions of the two disorder components is equivalent to a rotation of approximately 60° about the C-N single bond. In the crystal, the mol-ecules are held together by O-H⋯N hydrogen bonds, forming simple C(5) chains along the b-axis direction. In addition, pairs of the chains are further aggregated by weak C-H⋯π inter-actions.

Project description:In the title compound, C(13)H(18)ClNO(4), the two meth-oxy groups at the meta positions of the attached benzene ring are close to being coplanar with the ring [the meth-oxy C atoms deviate by 0.267 (7) and 0.059 (7) Å], whereas the third meth-oxy group at the para position is not coplanar with the benzene ring [methoxy C atom deviates by 1.100 (6) Å]. In the crystal, mol-ecules are linked into a chain along the a axis by O-H⋯N hydrogen bonds.

1,3-Bis{(E)-[4-(di-methyl-amino)-benzyl-idene]amino}-propan-2-ol: chain structure formation via an O-H⋯N hydrogen bond.

Project description:The asymmetric unit of the title compound, C21H28N4O, consists of two unique mol-ecules linked by an O-H⋯N hydrogen bond. The conformation of both C=N bonds is E and the azomethine functional groups lie close to the plane of their associated benzene rings in each of the independent mol-ecules. The dihedral angles between the two benzene rings are 83.14 (4) and 75.45 (4)°. The plane of the one of the N(CH3)2 units is twisted away from the benzene ring by 18.8 (2)°, indicating loss of conjugation between the lone electron pair and the benzene ring. In the crystal structure, O-H⋯N hydrogen bonds together with C-H⋯O hydrogen bonds link neighbouring supra-molecular dimers into a three-dimensional network.

Project description:The title compound, C(22)H(22)O(5), crystallizes with two independent mol-ecules in the asymmetric unit, both of which possess pseudo-C(s) symmetry.

The crystal packing is influenced by ?-stacking inter-actions of the parallel displaced type [centroid-centroid distance of 3.723?(1)?Å for mol-ecule 1 and 3.884?(1)?Å for mol-ecule 2, with ring slippages of 1.432 and 1.613?Å, respectively] and the T-shaped type, with the long mol-ecular axes all aligned along [010].
