(OC-6-35)-(2,2′-Bipyridine-κ²N,N′)dimethyl(3-sulfidopropionato-κ²S,O)platinum(IV)

Abstract

Key indicators: single-crystal X-ray study; T = 150 K; mean (C-C) = 0.006 Å; R factor = 0.026; wR factor = 0.049; data-to-parameter ratio = 24.3.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 0 -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 thiolatecarboxylate chelate ring and the constrained bipyridine group. The crystal packing appears to be controlled by a combination of -stacking [centroid-centroid distance = 3.611 (2) Å ] and C-HÁ Á ÁO interactions. Related literature
