organic compounds
The title Schiff base compound, C28H26N2O2, possesses both OH and NH tautomeric character in its molecular structure. While the OH side of the compound is described as an intermediate state, its NH side adopts a predominantly zwitterionic form. The molecular structure of the compound is stabilized by both N+—HO− and O—HN intramolecular hydrogen bonds. There are two weak C—HO hydrogen bonds leading to polymeric chains of topology C(5) and C(13) running along the b axis of the unit cell. In addition, intermolecular C—Hπ interactions serve to stabilize the extended structure.
organic compounds
Molecules of the title compound, C24H19NO6S, adopt the Z configuration and have a distorted tetrahedral geometry around the S atom. The oxazolone, 2-phenyl and methoxyphenyl rings are approximately coplanar. The C atom between the methoxyphenyl and oxazolone rings displays a distorted trigonal bonding geometry. Pairs of molecules are linked into dimers through weak C—HO hydrogen bonds.
metal-organic compounds
The title complex, [PdCl2(C21H26N2)(C18H15P)], shows slightly distorted square-planar coordination around the PdII metal centre. The Pd—C bond distance between the N-heterocyclic ligand and the metal atom is 2.028 (5) Å. The dihedral angle between the two trimethylphenyl ring planes is 36.9 (2)°.
