The asymmetric unit of the title compound, C44H32P2, conventionally abbreviated BINAP, is one half of the complete chiral BINAP molecule, which adopts a C2 crystallographic point-group symmetry with a twofold axis splitting the molecule in two identical halves; a center of symmetry between molecules further determines the racemic pairs. There are no obvious supramolecular interactions between adjacent BINAP molecules.
