Bis[N,N-bis-(diphenyl-phosphan-yl)cyclo-penta-namine-κ²P,P']platinum(II) bis-(trifluoro-methane-sulfonate).

The title compound, Pt(C₂₉H₂₉NP₂)₂₂, consists of a Pt(II) atom, situated on an inversion centre, coordinated by two diphosphinoamine bidentate ligands and charge-balanced by two trifluoro-methane-sulfonate 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 cyclo-pentane ring is slightly twisted: the puckering parameters are q(2) = 0.420 (5) Å and ϕ = 26.5 (8) °. The trifluoro-methane-sulfonate anion displays a 0.511 (11):0.489 (11) positional disorder. Weak inter- and intra-molecular C-H⋯O hydrogen bonds influence the crystal packing.
