[4-Amino-N-(pyrimidin-2-yl)benzenesulfonamido-N](triphenylarsine-As)gold(I)

L. L. Marques, E. S. Lang and R. A. Burrow

Abstract: The title compound, [Au(C₁₀H₉N₄O₂S)(C₁₈H₁₅As)], is isostructural with the triphenylphosphine analog [Lang et al. (2003). Acta Cryst. C59, m95-m96]. The geometry is nearly linear at the Au^I center, with Au-N = 2.0552 (15) Å, Au-As = 2.3266 (6) Å and N-Au-As = 171.56 (4)°. The molecules are joined by intermolecular N-HO bonds between the amine and sulfonyl groups of the sulfadiazine ligand. The slightly shorter Au-N distance in the title compound compared to its triphenylphosphine analog is due to packing effects.
