The title compound, cis-[PtCl2(C4H10S)2], crystallizes in the space group P21/n with pseudo-square-planar coordination geometry. The orientation of the ethyl groups on the S atoms is staggered with respect to the coordination plane, giving the complex approximate C 2v symmetry. The complex does not form dimeric packing units with short Pt...S intra-dimeric distances as seen in some related complexes, but instead displays C - H...Cl inter-actions in three dimensions. These C - H...Cl - Pt contacts are compared with those of related compounds reported in the Cambridge Structural Database, which show a frequency maximum in the range 120-170° for the C - H...Cl angle.

The new ligand precursors [1-(Me3Si)-4-(R){C6(CH2NMe2) 4-2,3,5,6}] (2, R = Me3Si; 3, R = H) have been used for the preparation of ionic 1,4-phenylene-bridged bispalladium(II) and palladium(II)-platinum(II) complexes [1-{M(MeCN)}-4-{M′(MeCN)}{C6(CH2NMe 2)4-2,3,5,6}]-(BPh4)2 (5b, M = M′ = Pd; 10, M = Pd, M′ = Pt). Lithium-halogen exchange of the new ligand precursor C6Br2(CH2NMe2)4-2,3,5,6, 11, generates a presumably polymeric organodilithium reagent, 12, which in a transmetalation reaction with [PtCl2(Et2S)2] affords the 1,4-phenylene-bridged bisplatinum complex [1,4-(PtCl)2{C6(CH2NMe2) 4-2,3,5,6}], 13. Reaction of colorless 13 with SO2 affords the unique orange bis-SO2 adduct [1,4-{PtCl(η1-SO2)}2{C6(CH 2NMe2)4-2,3,5,6}], 16, of which an X-ray crystal structure has been determined. The ionic derivative [1,4-{Pt(MeCN)}2{C6(CH2NMe2) 4-2,3,5,6}](BPh4)2, 14b, obtained by reaction of 13 with AgOTf in MeCN followed by addition of NaBPh4, has been the subject of an X-ray crystal structure determination. The X-ray molecular structures of 5b, 10, and 14b have been determined and show intramolecular M?M distances of ca. 6.5 A?. The bistriflate complex [1,4-{Pt(MeCN)}2{C6(CH2NMe 2)4-2,3,5,6}](OTf)2,14a, has also been used for the synthesis of the organometallic polymer {[1,4-{PtI(μ-I)}2{C6(CH2N(H)Me 2)4-2,3,5,6}]n}-(OTf)2n, 24. Triflate complex 14a slowly reacts with iodomethane to afford the dark red air-stable crystalline complex [1,4-{PtI}2{C6Me-1-(CH2NMe2) 4-2,3,5,6}](OTf), 23. The X-ray molecular structure of 23 shows it to be a unique arenium ion species with two para-oriented σ-bonded iodoplatinum substituents.
