(η(6)-Isopropyl N-phenyl­carbamate)(η(5)-penta­methyl­cyclo­penta­dien­yl)ruthenium(II) tetra­phenyl­borate acetone monosolvate

The title complex, [Ru(C(10)H(15))(C(10)H(13)NO(2))](C(24)H(20)B)·C(3)H(6)O, is related to the analogous O-methyl complex. The average Ru—C distance to the penta­methyl­cyclo­penta­dienyl (Cp*) group is 2.19 (3) Å, and 2.21 (1) Å to the ortho, meta and para C atoms of the arene ring. The Ru—C(ipso) bond length of 2.272 (3) Å is significantly longer, reflecting movement of the Ru atom away from the C atoms with electronegative substituents attached. The amide H atom in the cation forms an inter­molecular N—H⋯O hydrogen bond with the carbonyl O atom of the acetone solvent mol­ecule. A C—H⋯O inter­action also occurs.
