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
In the title complex, [Au(C 26 H 48 P 2 ) 2 ]ClÁ4CHCl 3 , the cation and anion lie on twofold rotation axes. The Au atom has a distorted tetrahedral coordination geometry, with two chelating diphosphine ligands, and lies far from the anion.
