organic compounds
In the title compound, C24H27N3O2S·C2H6O, the dihedral angle between the least-squares planes of the 2,5-dihydroxybenzene ring and the mesityl group is 78.59 (6)°. An intramolecular O—HN hydrogen bond is observed in the molecular structure. Centrosymmetrically related molecules are linked by N—HO intermolecular hydrogen bonds to form a dimer. The dimers are interlinked by O—HO and O—HN intermolecular hydrogen bonds involving the ethanol molecule of crystallization to form chains along the a axis.
metal-organic compounds
The title molecule, [Ni(C10H12N3O3)2], possesses a crystallographic centre of symmetry at the NiII atom. The coordination geometry around the NiII atom is distorted square planar, consisting of four N atoms from two oxime ligands. The crystal packing shows two-dimensional polymeric chains, which are stabilized by a hydrogen-bonded network, and other weak intermolecular interactions.
