Bis(1-{bis­[2-(diphenyl­phosphino­yl)eth­yl]phosphan­yl}-2-(diphenyl­phosphan­yl)ethane)dinitratoplatinum(II) methanol tetra­solvate

In the title compound, [Pt(NO₃)₂(C₄₂H₄₂O₂P₄)₂]·4CH₃OH, the Pt atom positioned on a crystallographic centre of inversion. The two symmetry-equivalent nitrate anions are weakly coordinated to the Pt^II ion, creating, together with four P ligand atoms, a distorted octa­hedral coordination environment. In addition, several close C—H...O contacts between the nitrate O atoms and phenyl H atoms are found. Hydrogen bonds from two methanol solvent mol­ecules to one of the O—P groups complete the crystal structure.

S1. Comment

The title compound, [Pt(L)₂]²⁺ (NO₃^-)₂ (L = (P1,P1-bis(2-(diphenylphosphinoxid)ethyl)-P2,P2-diphenylethane -1,2-diphosphine), crystallizes as a packing of a discrete dication and two nitrate anions with the Pt-atom positioned on a centre of inversion. The two symmetry equivalent ligands molecules L are coordinated to the Pt-center by two phosphine donor atoms P1 and P2 with Pt—P distances (d(Pt—P1) = 2.3399 (9) Å, d(Pt—P2) = 2.3236 (9) Å) (Table 1) creating a square planar coordination environment in accord with previously reported Pt^II tetraphosphine complexes (Brüggeller et al., 1992). The two additional phosphor oxide groups of the ligands are not coordinated to the metal centre in the solid state. A long distance of d(Pt1—O4) = 3.524 (3) Å, angles of P1—Pt—O4 of 104.36 (5) ° and P2—Pt—O4 of 99.77 (5) ° are indicative of a weak Pt—NO₃^- interaction which is much weaker than a previously reported Pt^II—NO₃^- distance of 2.116 Å in a related complex (Fernandez et al., 2001). The nitrate anion is packed within a cavity created by the coordinated phosphine ligand atoms above and due to symmetry below the square plane spanned by the four phosphor ligand atoms creating a distorted octahedral coordination environment around the Pt^II ion. In addition several close C—H···O contacts between 2.30 and 2.70 Å were found between ortho-phenyl protons and methylene protons with nitrate oxygen atoms. Two methanol molecules with O—H···O hydrogen bonds to one of the O—P groups (Table 2) complete the crystal packing. The second P—O1 fragment exhibits weak hydrogen bond interactions with d(O1—H17A) of 2.997 Å and d(O1—H18A) of 2.991 Å to one of the adjacent phenyl group hydrogen atoms.

S2. Experimental

All reactions were carried out under an atmosphere of dry nitrogen using standard Schlenk techniques. Solvents were dried and stored under nitrogen. Platinum(II)nitrate was purchased from ChemPur and Tris(2-(diphenylphosphino)ethyl)-phosphine was obtained from Acros Organics.

150 mg (0.47 mmol) Platinum(II)nitrate was dissolved in 50 ml water and 50 ml e thanol was added. 315 mg (0.47 mmol) Tris(2-(diphenylphosphino)ethyl)- phosphine (PP3) was dissolved in dichlormethane and added to the reaction mixture. The suspension was stirred at room temperature for 3 days. Afterwards the mixture was concentrated to small volume and a yellow solid precipitated. The precipitate was filtered and dried in vacuo. Single crystals were received by gas phase diffusion of diethyl ether into a solution of the yellow product in methanol.

S3. Refinement

All non-hydrogen atoms were refined anisotropically and H atoms were refined using riding constraints with C—H distances set to 0.95 Å for aromatic, to 0.99 Å for aliphatic, 0.98 Å for methanol C—H bonds and 0.84 Å for O—H bonds. U_iso(H) values were set to 1.2 U_eq of the parent atom.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
