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-actions between adjacent BINAP mol-ecules.
