Bis(cyclo-octa-1,5-diene)platinum reacts with benzo-1,4-quinone, 2,3,5,6-tetramethyl-, 2,6-dimethyl-, 2,6-di-t-butyl-, 2,5-dimethyl-, and 2,5-diphenyl-benzo-1,4-quinone to give complexes a = 10.652(5), b = 12.542(4), c = 14.971(4) Angstroem, and β = 93.17(3) deg.The structure has been refined to R 0.025 (R' 0.027) for 4 258 independent reflections collected at 200 K to 2.9 < or = 2θ < or = 60 deg (Mo-Kα X-radiation).The results establish that the 2,6-di-t-butylbenzo-1,4-quinone ligand is attached to the metal by both C=C bonds so that with the cod group the platinum atom is in a distorted tetrahedral environment (dihedral angle between the pairs of double bonds of the ligands is 69 deg).In the complexes
