In the title compound, [PtCl2(C9H7N)2]·CH3NO2, the PtII cation is four-coordinated in an essentially square-planar environment by two N atoms from two quinoline ligands and two Cl− anions. One of the nearly planar quinoline ligands [maximum deviations = 0.042 (6) and 0.018 (7) Å] is almost perpendicular to the PtCl2N2 unit [maximum deviation = 0.024 (3) Å], making a dihedral angle of 89.6 (1)°, whereas the other is slightly inclined to the central plane with a dihedral angle of 74.1 (1)°. The dihedral angle between the quinoline ligands is 88.3 (2)°. In the crystal, each solvent molecule is linked to the metal complex by weak intermolecular C—H⋯O hydrogen bonds.

To a solution of K2PtCl4 (0.2074 g, 0.500 mmol) in H2O (20 ml) was added quinoline (0.1304 g, 1.010 mmol), and refluxed for 3 h. The formed precipitate was separated by filtration, washed with H2O and EtOH, and dried at 50°C, to give a yellow powder (0.1761 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from a CH3NO2 solution at room temperature.
H atoms were positioned geometrically and allowed to ride on their respective parent atoms: C—H = 0.95 Å (CH) or 0.98 Å (CH3) with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C). The highest peak (2.69 e Å-3) and the deepest hole (-1.38 e Å-3) in the difference Fourier map are located 0.86 Å and 0.75 Å, respectively, from the Pt1 atom.
The
of the title compound, [PtCl2(quinoline)2].CH3NO2, contains a neutral PtII complex and a nitromethane solvent molecule (Fig. 1). In the complex, the PtII ion is four-coordinated in an essentially square-planar environment by two N atoms from two quinoline ligands and two Cl- anions (Table 1). The Cl atoms are in conformation with respect to each other, like in the analogous PtII complex [PtCl2(quinoline)2].0.25DMF (DMF = N,N-dimethylformamide) (Davies et al., 2001). By contrast, in the related PdII complex [PdCl2(quinoline)2], the Cl atoms are in conformation (Ha, 2012).One of the nearly planar quinoline ligands [maximum deviations = 0.042 (6) Å and 0.018 (7) Å] is almost perpendicular to the PtCl2N2 unit [maximum deviation = 0.024 (3) Å], making dihedral angle of 89.6 (1)°, whereas the other is slightly inclined to the unit plane with a dihedral angle of 74.1 (1)°. The dihedral angle between the quinoline ligands is 88.3 (2)°. In the crystal, each solvent molecule is linked to the complex by intermolecular C—H···O hydrogen bonds (Fig. 2 and Table 2). Moreover, the complex molecules display numerous intermolecular π-π interactions between adjacent six-membered rings, the shortest ring centroid-centroid distance being 3.617 (5) Å.

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. |

The asymmetric unit of the title compound, [PtCl2(quinoline)2].CH3NO2, contains a neutral PtII complex and a nitromethane solvent molecule (Fig. 1). In the complex, the PtII ion is four-coordinated in an essentially square-planar environment by two N atoms from two quinoline ligands and two Cl- anions (Table 1). The Cl atoms are in cis conformation with respect to each other, like in the analogous PtII complex [PtCl2(quinoline)2].0.25DMF (DMF = N,N-dimethylformamide) (Davies et al., 2001). By contrast, in the related PdII complex [PdCl2(quinoline)2], the Cl atoms are in trans conformation (Ha, 2012).
One of the nearly planar quinoline ligands [maximum deviations = 0.042 (6) Å and 0.018 (7) Å] is almost perpendicular to the PtCl2N2 unit [maximum deviation = 0.024 (3) Å], making dihedral angle of 89.6 (1)°, whereas the other is slightly inclined to the unit plane with a dihedral angle of 74.1 (1)°. The dihedral angle between the quinoline ligands is 88.3 (2)°. In the crystal, each solvent molecule is linked to the complex by intermolecular C—H···O hydrogen bonds (Fig. 2 and Table 2). Moreover, the complex molecules display numerous intermolecular π-π interactions between adjacent six-membered rings, the shortest ring centroid-centroid distance being 3.617 (5) Å.
