چکیده
In the title compound, C(26)H(18)O(2), the mol-ecule is located on a twofold rotation axis. The two naphthyl ring planes in the mol-ecule are nearly perpendicular to each other [dihedral angle = 82.42 (1)°. No classical hydrogen bonds or aromatic π-π stacking inter-actions were observed.

The asymmetric unit of the title compound, C(44)H(32)P(2), conventionally abbreviated BINAP, is one half of the complete chiral BINAP mol-ecule, which adopts a C2 crystallographic point-group symmetry with a twofold axis splitting the mol-ecule in two identical halves; a center of symmetry between mol-ecules further determines the racemic pairs. There are no obvious supra-molecular inter-action...

The asymmetric unit of the title compound, C(24)H(22)O(4), contains two independent mol-ecules in both of which the naphthalene ring systems adopts a transoid arrangement. The dihedral angles between the naphthalene ring system in the two mol-ecules are 83.0 (1) and 89.0 (1)°. There are slight differences in the C(H(3))-O-C(H(2))-O- torsion angles of the eqivalent meth-oxy-meth-oxy groups. In t...

In the title complex, [RhCl(C(44)H(32)OP(2))]·CH(3)OH, the Rh(I) ion is coordinated by a naphthyl group of a partially oxidized 2,2'-bis-(diphenyl-phosphan-yl)-1,1'-binaphthyl (BINAP) ligand in a η(4) mode, one P atom of the diphenyl-phosphanyl group and one Cl atom. The P=O group does not inter-act with the Rh(I) ion but accepts an O-H⋯O hydrogen bond from the methanol solvent mol-ecule.
