Tetrachlorido(1,10-phenanthroline-[kappa]2N,N')platinum(IV) acetonitrile hemisolvate

Abstract top

The asymmetric unit of the title compound, [PtCl4(C12H8N2)]·0.5CH3CN, contains two crystallographically independent PtIV complexes with very similar geometry and one solvent molecule. In the complexes, each PtIV ion is six-coordinated in a distorted octahedral environment by two N atoms of the 1,10-phenanthroline ligand and four Cl atoms. Because of the different trans effects of the N and Cl atoms, the Pt-Cl bonds trans to the N atom are slightly shorter than those trans to the Cl atom. The compound displays numerous intermolecular [pi]-[pi] interactions between six-membered rings, with a shortest centroid-to-centroid distance of 3.654 Å. There are also weak intra- and intermolecular C-H...Cl hydrogen bonds.

Comment top

The asymmetric unit of the title compound, [PtCl4(C12H8N2)].0.5CH3CN, contains two crystallographically independent PtIV complexes with identical geometry and a CH3CN solvent molecule (Fig. 1 and 2). In the complexes, each Pt4+ ion is six-coordinated in a distorted octahedral environment by two N atoms of the 1,10-phenanthroline ligand and four Cl atoms. The main contributions to the distortion are the tight N—Pt—N chelate angles (82.0 (2)° and 80.9 (2)°), which result in non-linear trans axes (Cl—Pt—N = 174.7 (2)–175.7 (2)°, Cl—Pt—Cl = 177.57 (8)° and 175.68 (7)°). Because of the different trans effects of the N and Cl atoms, the Pt—Cl bonds trans to the N atom (lengths: 2.294 (2), 2.297 (2), 2.301 (2) and 2.298 (2) Å; mean length: 2.298 (2) Å) are slightly shorter than bond lengths to mutually trans Cl atoms (lengths: 2.322 (2), 2.312 (2), 2.302 (2) and 2.309 (2) Å; mean length: 2.311 (2) Å). The compound displays numerous intermolecular π–π interactions between six-membered rings, with a shortest centroid–centroid distance of 3.654 Å. There are also weak intra- and intermolecular C—H···Cl hydrogen bonds (Table 1).

Experimental top

To a solution of K2PtCl6 (0.2026 g, 0.417 mmol) in H2O (10 ml) was added 1,10-phenanthroline (0.2162 g, 1.200 mmol) in MeOH (10 ml), and stirred for 5 h at room temperature. The formed precipitate was separated by filtration and washed with water and MeOH and dried under vacuum, to give a yellow powder (0.1710 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from a CH3CN solution.

Refinement top

H atoms were positioned geometrically and allowed to ride on their respective parent atoms [C—H = 0.93 (aromatic) or 0.96 Å (CH3) and Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C)].

Special details top

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.
