Reaction of CuI with 1 or 2 equivalent(s) N,N′-Bis(diphenylphosphino) -2,6-diaminopyridine (BDDP) gives two different complexes, [Cu(I)μ-(BDDP- κP,Npy)]2 (1) and [Cu(BDDP-κP,N py)2]I (2), in high yields. The determination of the molecular structure show that both CuI atoms are tetrahedrally coordinated, rather than a square-planar geometry reported for Cr0, NiII-BDDP complexes before, which contains a planar tridentate chelate ring system. The introduction of AuCl(tht) (tht = tetrahydrothiophene) into [Cu(BDDP-κP,Npy)2]I leads unexpectedly to the formation of a digold complex 2,6-[(ClAuPh2P)HN]2C 5H3N and dimeric [Cu(I)μ-(BDDP-κP,N py)]2.
