[N,N-Bis(diphenylphosphino)propylamine-κ²P,P′]dichloridoplatinum(II)

The Pt(II) atom in the title compound, [PtCl₂(C₂₇H₂₇NP₂)], has a highly distorted square-planar geometry, as evidenced by the P—Pt—P bite angle [72.4 (1)°]. The strain in the complex is further illustrated by the distorted tetrahedral angles of the P atoms, which range between 93.5 (1) and 122.2 (1)°. It is of interest to note that the N atom has to adopt an almost planar geometry with the two P atoms and the C atom attached to it [it is displaced by 0.093 (2) Å from the CP₂ plane] in order to accommodate the steric bulk of the phenyl groups and the alkyl group of the ligand coordinated to the Pt^II centre. The molecules pack in horizontal rows across the bc plane. C—H

Cl hydrogen bonds stabilize the crystal packing.

Comment top

In the title compound (Fig. 1 and Table 1), all bond distances and angles are considered to be normal and fall within range reported for similar complexes (Browning et al., 1992; Fei et al., 2006; Calabrò et al., 2004). The square-planar geometry of the complex is highly distorted with a P1—Pt—P2 bite angle of 72.40 (3)° and a Cl1—Pt—Cl2 angle of 92.7 (1). The reported P1—Pt—P2 small bite angle forces the P1—N1—P2 angle to 100.1 (1)° which illustrates the distorted geometry from the ideal tetrahedral geometry of the N atom. The distance between the N1 atom and the plane created by C1, P1 and P2 is 0.093 (2) Å. The P atoms are also severely distorted from the expected tetrahedral configuration with Pt—P1—N1 and Pt—P2—N1 angles being 94.0 (1) and 93.5 (1)°, respectively. The molecules of the title compound pack horizontal rows in the unit cell across the bc plane (Fig. 2). Intermolecular hydrogen bond exists between C1—H1A and Cl1(1/2+x, 1/2-y, -1/2+z) (Table 2).

Experimental top

Pt(cod)Cl₂ (50 mg, 0.13 mmol) (cod = 1,5-cyclooctadiene) was dissolved in dichloromethane (15 ml). Bis(diphenylphosphino)propylamine (57.1 mg, 0.13 mmol) was also dissolved in dichloromethane (10 ml) and was added dropwise to the Pt(cod)Cl₂ solution. The solution was stirred for 2 h at room temperature. The reaction mixture was layered with methanol (10 ml). Colourless single crystals suitable for X-ray crystallography was obtained after 1 d (yield 0.066 g, 73.4%).
