Bis[N,N-bis­(diphenyl­phosphan­yl)cyclo­penta­namine-κ²P,P′]platinum(II) bis­(trifluoro­methane­sulfonate)

The title compound, [Pt(C₂₉H₂₉NP₂)₂](CF₃SO₃)₂, consists of a Pt^II atom, situated on an inversion centre, coordinated by two diphosphinoamine bidentate ligands and charge-balanced by two trifluoro­methane­sulfonate anions. The Pt^II atom has a distorted square-planar geometry defined by the four P atoms. The distortion is illustrated by the P—Pt—P bite angle of 70.31 (4)°. The geometry around the N atom deviates from a trigonal–planar geometry, evidenced by the P—N—P bite angle of 102.3 (2) °. The N atom is displaced by 0.114 (4) Å from the C/P/P plane. In order to coordinate, the orientation of the phenyl rings alters from a C_s conformation to a C_2v conformation. The cyclo­pentane ring is slightly twisted: the puckering parameters are q₂ = 0.420 (5) Å and φ = 26.5 (8) °. The trifluoro­methane­sulfonate anion displays a 0.511 (11):0.489 (11) positional disorder. Weak inter- and intra­molecular C—H...O hydrogen bonds influence the crystal packing.

Tricarbonylbis­(triphenyl­phosphane-κP)iridium(I) hexa­fluoridophosphate methanol monosolvate

In the title compound, [Ir(C₁₈H₁₅P)₂(CO)₃]PF₆·CH₃OH, the Ir^I atom is coordinated by two triphenyl­phosphine ligands in axial sites and three carbonyl ligands in the equatorial plane of a fairly regular trigonal bipyramid: the equatorial C—Ir—C angles range from 115.45 (9) to 126.42 (10)°. The small deviations from the ideal tetra­hedral geometry around the P atoms are illustrated by C—P—C angles ranging from 104.08 (9) to 106.46 (9)°. In the crystal, the mol­ecules are linked by weak C—H...F, C—H...O and C—H...π inter­actions.
