[Bis(2-diphenylphosphinoethyl) sulfide-κ³P,S,P′](triphenylphosphine-κP)platinum(II) diperchlorate acetone solvate

Abstract

In the title compound, [Pt(C(18)H(15)P)(C(28)H(28)P(2)S)](ClO(4))(2*-)C(3)H(6)O or [Pt(PPh(3))(PSP)](ClO(4))(2*) x CH(3)COCH(3), where PSP is the potentially tridentate chelate ligand bis(2-diphenylphosphinoethyl) sulfide, all three donor groups of the PSP ligand are coordinated to the central Pt atom, with Pt[bond]P = 2.310 (1) A and Pt[bond]S = 2.343 (1) A. The fourth coordination site is occupied by the P donor of the triphenylphosphine ligand [Pt[bond]P = 2.289 (1) A]. The complex cation has exact mirror symmetry, with the S atom, the Pt atom and the P atom of the PPh(3) ligand in the mirror plane. The Pt atom has a distorted square-planar coordination geometry. A pi[bond]pi interaction is present between the phenyl rings of the PPh(3) ligand and the terminal -PPh(2) group of the PSP chelate.

POP-type ligands: Variable coordination and hemilabile behaviour

“…Examples of transition metal complexes containing the PSP ligand (114) have been structurally characterised, where the ligand can bind in both cis-j 2 -P,P [83] and mer-j 3 -P,S,P geometries [84][85][86][87]. Isomerisation between fac-j 3 -P,S,P and mer-j 3 -P,S,P complexes of 114 has also been reported [87].…”

“…The chemical structures and practical applications of these particular complexes are presented in Table S3. In triclinic [Pt{η 3 -Ph2P(C6H4)S(=O)(C6H4)PPh2}(P 3 Ph3)]0.5.CH2Cl [48] (at 100 K) and orthorhombic [Pt{η 3 -Ph2P(CH2)2S(CH2)2PPh2}(P 3 Ph3)]ClO4 [50] (at 100 K), the P 3 Ph3 are involved (PtP 1 S 1 P 2 P 3 ).…”
