2,2'-(1-Phenyl-1H-pyrazole-3,5-di-yl)diphenol.

ABSTRACT: The title compound, C(21)H(16)N(2)O(2), was derived from 1-(2-hydroxy-phen-yl)-3-(-methoxy-phen-yl)propane-1,3-dione. The mol-ecular structure of the title compound is stabilized by an intra-molecular O-H?N hydrogen bond. The dihedral angle between the hydroxy-phenyl ring involved in this intra-molecular hydrogen bond and the pyrazole ring is significantly smaller [10.07?(6)°] than the dihedral angle between the pyrazole and the other hydroxy-phenyl ring [36.64?(5)°]. The benzene ring makes a dihedral angle of 54.95?(3)° with the pyrazole ring. The crystal packing is stabilized by O-H?O and O-H?N hydrogen bonds.

2,2'-[(4-Methyl-2-phenyl-imidazolidine-1,3-di-yl)bis-(methyl-ene)]diphenol.

Project description:The methyl-substituted imidazolidine ring of the title compound, C24H26N2O2, adopts an envelope conformation with the N atom adjacent to the methyl-ene group as the flap. The meth-yl-ethyl-ene fragment in this ring is disordered over two positions with an occupancy ratio of 0.899?(4):0.101?(4). The hy-droxy-benzyl groups are inclined at 71.57?(15) and 69.97?(19)° to the mean plane of major disorder component of the heterocyclic ring with an inter-planar angle between the two hy-droxy-benzyl groups of 66.00?(5)°. The phenyl substit-uent approaches a nearly perpendicular orientation relative to the mean plane of the imidazolidine ring, making a dihedral angle of 75.60?(12)°. This conformation is stabilized by two intra-molecular O-H?N bonds, which generate S(6) ring motifs.

2,2'-(4-Amino-4H-1,2,4-triazole-3,5-di-yl)diphenol.

Project description:The structure of the title compound, C(14)H(12)N(4)O(2), was determined as part of a project on the coordination chemistry of 1,2,4-triazole derivatives. In the crystal structure, one of the two benzene rings is almost coplanar with the five-membered triazole ring (mean deviation = 0.019?Å), whereas the second benzene ring is rotated by 51.973?(2)°. The two N-C-N-N torsion angles [170.365?(2) and -170.942?(3)°] indicate that the amido group is slightly twisted away from the triazole plane. An intra-molecular O-H?N hydrogen bond occurs. In the crystal structure, inter-molecular N-H?O and O-H?N hydrogen bonding is found.

1-Benzyl-2-phenyl-1H-benzimidazole-4,4'-(cyclo-hexane-1,1-di-yl)diphenol (1/1).

Project description:The asymmetric unit of the title co-crystal, C(20)H(16)N(2)·C(18)H(20)O(2), contains one mol-ecule of 4,4'-(cyclo-hexane-1,1-di-yl)diphenol (in which the cyclo-hexane ring adopts a chair conformation) and one mol-ecule of 1-benzyl-2-phenyl-1H-benzimidazole, which are paired through an O-H?N hydrogen bond. These pairs are further linked by inter-molecular O-H?O hydrogen bonds into chains along [010]. Weak inter-molecular C-H?O and C-H?? inter-actions further consolidate the crystal packing. The dihedral angles between the pendant phenyl rings and the benzimidazole ring are 86.9?(2) and 43.1?(2)°.
