“…[PhP(OH)Se 2 ] À anions were formed during the course of the reaction. The substitution pattern at the phosphorus atom in 2 is rare and only few examples of P-based ligands are known which both contain hydroxyl groups and Se atoms [18]. Crystals of 2 were soluble in THF-d 8 [19].…”

“…The crystal structure of a pale yellow triclinic complex exhibits a [Pt 3 (μ 3 -S) 2 (μ-η 2 -dppe) 3 ] 2+ cation with D 3 symmetry, 99 comprised of three fused, slightly distorted square planar (dppe)PtS 2 units. The central Pt 3 S 2 core is nearly regularly trigonal bipyramidal with Pt-Pt distances in the range 3.093(3) to 3.140(3) Å and an average Pt-S distance of 2.366 Å.…”

Organodiphosphines are very useful as soft P,P donor ligands in the chemistry of platinum. In this review are summarized and analyzed almost 200 Pt(II) complexes that contain at least one organodiphosphine ligand. There are Pt(II) atoms in a square planar environment with a wide variability of inner coordination spheres: PtP 4 , PtP 3 X (X = H, Cl, S, Br), PtX 2 P 2 (X = O, N, C, B, Cl (most common), S, Br, Se, Si, I, Te), PtP 2 XY (XY = H+O, H+Cl, H+Si, O+N, O+Si, N+S, N+Se, Cl+Si). The cis derivatives, by far, prevail. There are four basic Pt P (organodiphosphine) bond distances and their mean values elongated in the order: 2.270 Å (chelated) < 2.290 Å (bridged) < 2.322 Å (trans to C) < 2.348 Å (trans to H). Organodiphosphines form a wide variability of metallocycles from 4-to even 20-membered, with 4-and 5-membered being the most common ring size. Some examples exist as isomers, differing mostly by the degree of distortion and are examples of distortion isomerism. In the series of monomeric Pt(II) complexes, the mean Pt P (bidentate) bond distance elongated in the order: 2.235 Å (PtP 2 X 2 ) < 2.270 Å (PtP 2 XY) < 2.290 Å (PtP 3 X) < 2.320 Å (PtP 4 ).

“…There has recently been a report of the crystal structure of the [Pt 3 (dppe) 3 S 2 ] 2+ dication, which contains two face capping S 2− anions ( Figure 32). 77 The disulfide anion S 2 2− can coordinate edge-on (see Side-on Coordination), or bridge two or more central metal atoms The most common are illustrated in Figure 33. End-On Coordination of S 2 2− is not well established although, there has been a recent example with Cu(I) 78 As can be seen, a wide range of coordination types is known.…”
