Multinuclear magnetic resonance studies of the reactions of bidentate ligands with platinum(2+) O,O'-diethyl dithiophosphate. Crystal and molecular structure of [(diphenylarsinoethyl)diphenylphosphine sulfide][O,O'-diethyl dithiophosphato]platinum

Epimerization, diastereoselectivity and hemilability in dicationic chiral ruthenium complexes with bidentate (P∧S) bisphosphine monosulfide ligands

“…This phosphorus is coupled through the metal to the phosphorus nucleus of the arene-tethered ligand ( 2 J P-P = 35.7 Hz), as well as to the phosphine sulfide with J P-P = 19.7 Hz. This latter coupling is decreased with respect to the free ligand (49 Hz) [18], which is the usual observation [18][19][20][21][22] and is indicative of a spin coupling contribution of opposite sign through the metal and thus indicates the coordination of the sulfur to the metal. Likewise, the phosphine of the arene-tethered ligand shows a coupling to the directly coordinated phosphine of diphos(S), but an additional smaller 3 J coupling of 19.7 Hz to the phosphorus atom (the P V ) bound to the sulfur is observed.…”

Crystal Structure of Bis(triphenylphosphine)palladium(II) Isopropyldithiophosphate

“…Although Pd-P bond distances are in the range reported in a number of Pd(II) phosphine complexes 2,3 , one of the bonds Pd1-P3 is slightly longer (ca. 0.02 Å) than the other.…”

Synthesis and Carbonylation of Platinum(II) Organometallic Complexes with Bis(phosphanyl) Monosulfides − Crystal Structures of [κ2P,S‐{Ph2CH2P(S)Ph2}Pt(CH3)(Cl)] and [κP,μ‐κS‐{Ph2CH2CH2P(S)Ph2}Pt‐(CH3)]2[BF4]2

“…The usual [7,9,17,21] lowering in the bis(phosphanyl) monosulfide ( 31 P, 31 P) coupling constants is observed in both the neutral and cationic complexes: compared with the 2/3 J(P,P) of the free ligands [for dppmS 2 J(P,P) ϭ 79 Hz, for dppeS 3 J(P,P) ϭ 49 Hz], a decrease of 50 Hz and 41 Hz was found for 1 and 2 and a decrease of 55 Hz and 42 Hz was found for 3 and 4, respectively (Table 1).…”
