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.

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  ...[more]
