10-(tert-Butyl­dimethyl­silyl)-4,6-bis­(diphenyl­phosphino)phenoxazine

The title compound, C₄₂H₄₁NOP₂Si, used as a nixantphos-type ligand in homogeneous catalysis, crystallizes with one mol­ecule in the asymmetric unit. The mol­ecule has nearly mirror symmetry with N, O and Si on the pseudo-mirror plane, but it is not located on a crystallographic mirror plane. The most important feature of the mol­ecule is the intra­molecular P-P distance of 4.1453 (12) Å. The bond angles involving the P atoms are in the range 100.32 (14)-103.04 (15)°.

rac-(1S,11S,15S)-1-Hydroxy­methyl­bicyclo­[9.3.1]penta­decan-15-ol

The mol­ecule of the title compound, C₁₆H₃₀O₂, features a trans-fused bicyclic system. The six-membered ring has a chair conformation. The mol­ecules are linked via an O—H...O hydrogen bond [O...O = 2.7696 (11) Å and O—H...O = 174.2 (13)°] to form chains along the b axis. An intra­molecular O—H...O hydrogen bond [O...O = 2.6722 (11) Å and O—H...O = 148.4 (13)°] is present.
