(η⁴-Cycloocta-1,5-diene)(2-pyridinethiolato N-oxide-κO,κS)iridium(I)

The title compound, [Ir(C₅H₄NOS)(C₈H₁₂)], contains an Ir atom in an approximately square-planar environment if we consider the coordination plane formed by the midpoints of the double bonds of the cyclooctadiene ligand together with the S and O atoms [deviation from least squares plane is 0.01 (5) Å]. The S,O-ligand is also planar and the five-membered chelate ring has a bite angle of 84.4 (3)° at the Ir atom. Bond distances are Ir—S = 2.270 (4), Ir—O = 2.031 (9) and average Ir—C(olefinic) = 2.11 (2) Å.
