Abstract: 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)°.
