(OC-6-35)-(2,2′-Bipyridine-κ(2) N,N′)dimeth­yl(3-sulfido­propionato-κ(2) S,O)platinum(IV)

The title complex, [Pt(CH(3))(2)(SCH(2)CH(2)CO(2))(C(10)H(8)N(2))], is formed by the unusual oxidative addition of the disulfide, R (2)S(2) (R = CH(2)CH(2)CO(2)H), to (2,2′-bipyridine)­dimethyl­platin­um(II) with elimination of RSH. The product contains an unusual six-membered thiol­ate–carboxyl­ate chelate ring. This slightly distorted octa­hedral complex exhibits cis angles ranging from 77.55 (11) to 97.30 (8)° due to the presence of the thiol­ate–carboxyl­ate chelate ring and the constrained bipyridine group. The crystal packing appears to be controlled by a combination of π-stacking [centroid–centroid distance = 3.611 (2) Å] and C—H⋯O inter­actions.
