Tin, palladium and platinum derivatives of 1,1′-bis(diphenylphosphine)ferrocene. Crystal and molecular structures of 1,1′- bis-(diphenylphosphine)ferrocenedichloropalladium(II) and of 1,1′-bis(diphenylphosphine)ferrocenedichloroplatinum(II)

{1,1′-Bis[bis(5-methyl-2-furyl)phosphino]ferrocene-κ2P,P′}dichloroplatinum(II) dichloromethane hemisolvate

“…The environment at the Pt atom can be described as distorted squareplanar, with two cis-Cl atoms and two cis-P atoms. The P-Pt-P angle of 97.35 (4) and the Cl-Pt-Cl angle of 87.61 (4) agree well with values reported for structures of the type [P 2 PtX 2 ] (see, for example, De Lima & Filguerias, 1995). The Pt-P bond length of 2.241 (1) Å is slightly shorter than the corresponding bond length in PtCl 2 (dppf) (2.260 Å ).…”

Electrochemistry and complexation of Josiphos ligands

“…The P-Pt-P bite angle is slightly larger than the corresponding angle in the palladium analogue (Table 6). A similar trend has been noted in Pd(dppf)Cl 2 and Pt(dppf)Cl 2 [59,60]. As in the palladium analogue, the platinum in 2PtCl 2 is distorted from square planar geometry (Fig.…”

Synthesis and electrochemistry of late transition metal complexes containing 1,1′-bis(dicyclohexylphosphino)ferrocene (dcpf). The X-ray structure of [PdCl2(dcpf)] and Buchwald–Hartwig catalysis using [PdCl2(bisphosphinometallocene)] precursors

“…Pd adopts a pseudo-square planar geometry with the two P atoms cis, similar to dppf and dippf analogues [24,25]. In addition, the P-Pd-P angle of 102.45°is 4.47°larger than the corresponding angle of the dppf analogue [25] and 2.43°larger than the corresponding angle of the dppr analogue [37] ( Table 4); this difference can be attributed to the steric hindrance of the bulky cyclohexyl groups [42]. However, it is somewhat surprising that the corresponding angle in the dippf analogue is 1.14°larger than the angle in 2 [31].…”
