The Au^I ylide complex [Au((CH₂)₂PPh₂)]₂ (1) reacts oxidatively with nitroalkanes to form a Au^II product, [Au((CH₂)₂PPh₂)NO₂]₂ (2-NO₂). This complex was characterized by IR, NMR, and X-ray crystallography. The identity of the product was confirmed by the quantitative formation of 2-NO₂ from 1 and N₂O₄ brown gas . The product crystallizes in a monoclinic system C2/c: a = 12.159 (2) ?, b = 14.638 (2) ?, c = 16.536 (2) ?, β = 103.757 (11)°, and Z = 4 with R = 0.036 and R_w = 0.033.
