[(1,2,5,6-η)-Cyclo-octa-1,5-diene]bis-(4-methyl-phen-yl)platinum(II).

In the mononuclear title complex, [Pt(C(7)H(7))(2)(C(8)H(12))], the Pt(II) ion exhibits a square-planar coordination geometry defined by two methyl-phenyl ligands and the mid-points of the two π-coordinated double bonds of cyclo-octa-1,5-diene. The two methyl-phenyl groups have a cis relationship with a C-Pt-C bond angle of 88.54 (18)° and a dihedral angle between the mean planes of the benzene rings of 83.87 (1)°. Each complex mol-ecule links to four symmetry-related ones through inter-molecular C-H⋯π inter-actions, forming a layer almost parallel to the bc plane.
