4,4'-Dimethyl-2,2'-[imidazolidine-1,3-diylbis(methyl-ene)]diphenol.

ABSTRACT: The imidazolidine ring in the title compound, C(19)H(24)N(2)O(2), adopts a twist conformation and its mean plane (r.m.s. deviation = 0.19?Å) makes dihedral angles of 72.38?(9) and 71.64?(9)° with the two pendant aromatic rings. The dihedral angle between the phenyl rings is 55.94?(8)°. The mol-ecular structure shows the presence of two intra-molecular O-H?N hydrogen bonds between the phenolic hydroxyl groups and N atoms with graph-set motif S(6). In the crystal, C-H?O hydrogen bonds lead to the formation of chains along the b-axis direction.

In the crystal, the mol-ecules are linked by weak C-H⋯O inter-actions with a bifurcated acceptor, forming a three-dimensional network.

Project description:The crystal of the title Schiff base compound, C(19)H(20)Cl(2)N(2)O(2), contains of two crystallographically independent mol-ecules with similar conformations. In each mol-ecule, two intramolecular O-H⋯N bonds generate S(6) motifs. The N atoms are also in close proximity to two H atoms of the dimethyl-propane groups, with H⋯N distances between 2.59 and 2.62 Å. The imine group is coplanar with the benzene ring. The dihedral angles between the benzene rings in the two independent mol-ecules are 58.20 (12) and 47.95 (12)°. The structure displays short inter-molecular Cl⋯Cl [3.3869 (11) Å] and Cl⋯O [3.175 (2)-3.204 (2) Å] inter-actions. The crystal structure is further stabilized by weak inter-molecular C-H⋯O, C-H⋯π and π-π [centroid-centroid distances 3.6416 (13)-3.8705 (14) Å] inter-actions.

Crystal structure of the di-Mannich base 4,4'-di-chloro-3,3',5,5'-tetra-methyl-2,2'-[imidazolidine-1,3-diylbis(methyl-ene)]diphenol.

Project description:The title compound, C21H26Cl2N2O2, was prepared in a solvent-free microwave-assisted synthesis, and crystallizes in the ortho-rhom-bic space group Pna21. The imidazolidine ring adopts an envelope conformation and its mean plane is almost perpendicular to the two pendant aromatic rings [dihedral angles = 84.61 (9) and 86.54 (9)°]. The mol-ecular structure shows the presence of two intra-molecular O-H⋯N hydrogen bonds between the phenolic hy-droxy groups and imidazolidine N atoms. The two 3-chloro-6-hy-droxy-2,4-di-methyl-benzyl groups are located in a cis orientation with respect to the imidazolidine fragment. As a result, the lone pairs of electrons on the N atoms are presumed to be disposed in a syn conformation. This is therefore the first example of an exception to the 'rabbit-ears' effect in such 2,2'-[imidazolidine-1,3-diylbis(methyl-ene)]diphenol derivatives.

Two intra-molecular O-H?N hydrogen bonds with graph-set motif S(6) are present. No remarkable inter-molecular contacts exist in the crystal structure.
