The reaction of Ph2P(O)H with B(C6F5)(3) provided the Lewis pair complex Ph-2(H)POB(C6F5)(3) (5) containing a bipolar +P-O-B-linkage. The reaction of 5 with [(tht) AuCl] (tht = tetrahydrothiophene) proceeded with elimination of HCl and forma-tion of [{(C6F5)(3)BOPPh2} Au(tht)] (6), which can be regarded as push-pull complex between a zwitterionic OPPh2Au unit and a hard Lewis acid, B(C6F5)(3), coordinating at the oxygen atom, and a soft Lewis base, tht, coordinating at the gold atom.
