چکیده
The title compound, a Schiff base, C(24)H(31)NO(3), has a substituted aromatic ring at both ends of the azomethine linkage and these make a dihedral angle of 24.9 (1)°. There is an intra-molecular hydrogen bond between the hy-droxy group (donor) and the N atom of themazomethine linkage.

The title compound, C(35)H(35)NO(2)·CH(4)O, was obtained by the reaction of rac-2-amino-2-hy-droxy-1,1-binaphthyl and 3,5-di-tert-butyl-2-hy-droxy-benzaldehyde in absolute methanol. In the Schiff base mol-ecule, the two naphthyl bicycles are twisted by 71.15 (5)°. One hy-droxy group is involved in intra-molecular O-H⋯N hydrogen bond, while the methanol solvent mol-ecule is linked to another hy-...

The title amine, C(24)H(33)NO(3), has two substituted aromatic rings at either end of the -CH(2)NH- linkage [C(ar-yl)-CH(2)-NH-C(ar-yl) torsion angle = 77.4 (3)°]. The amino and hy-droxy groups are hydrogen-bond donors to the carbonyl O atom of an adjacent mol-ecule. These hydrogen bonds give rise to a chain that runs along the b axis. One of the tert-butyl groups is disordered over two positio...

The title compound, C(25)H(29)NO(3), is a Schiff base derivative of coumarin 120. There are two structurally similar but crystallographically independent mol-ecules in the asymmetric unit. Both mol-ecules exist in E configurations with respect to the C=N double bonds. The dihedral angles between the coumarin and 3,5-di-tert-butyl-2-hy-droxy-benzyl-idene ring planes are 4.62 (7) and 14.62 (7)° f...

The title compound, 2[Ce(C(51)H(75)N(4)O(3))]·C(4)H(10)O, was obtained in high yield (92%) by reduction of (TRENDSAL)Ce(IV)Cl [TRENDSAL is N,N',N''-tris-(3,5-di-tert-butyl-salicyl-ide-natoamino)-triethyl-amine] with potassium in THF. The bulky tripodal TRENDSAL ligand effectively encapsulates the central Ce(III) cation with a Ce-N(imine) distance of 2.860 (2) Å and an average C-N(amine) distanc...
