The crystal structure of the title compound, [(S)-(À)-BINAP] or C 44 H 32 P 2 , is enantiomorphous to the previously reported (R)-(+)-BINAP [Deeming et al. (1997). Organometallics, 16, 6004±6009], with effectively no differences in the molecular geometry apart from being of opposite absolute con®gur
