The interaction of chloro(triphenylphosphine)gold(I) and -bis with oxopurine derivatives under basic conditions has been investigated.The resulting complexes, 2(μ-L), , and containing one or two N-bonded gold(I) phosphine groups were characterized by means of 1H and 13C n.m.r. and i.r. spectroscopy.The crystal structure of the complex (theophyllinato)(triphenylphosphine)gold(I) was determined by X-ray crystallography.The compound is triclinic, space group P, with a=9.061(2), b=9.762(4), c=13.588(4) Angstroem, α=71.30(2), β=87.20(2), γ=86.10(2) degree, and Z=2.The structure was refined anisotropically to R=0.039 and R'=0.044, on the basis of 5150 observed reflections.The crystal contains discrete molecules (L = theophyllinate anion) with no unusually close intermolecular contacts.The co-ordination of the gold atom is almost linear, P-Au-N(7) 176.1(2) degree, with gold-nitrogen and gold-phosphorus bond distances of 2.047(6) and 2.231(2) Angstroem, respectively.Other bond lengths and bond angles are normal.The Au...O(6) distance of 3.317(6) Angstroem indicates that there is no significant gold-carbonyl bond.
