In the title complex, [PtCl4(C12H8N2)]·H2O, the Pt4+ ion is six-coordinated in a distorted octahedral environment by two N atoms of a 1,10-phenanthroline ligand and by four Cl atoms. As a result 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 intermolecular π–π interactions between the six-membered rings, with a centroid–centroid distance of 3.834 Å. There are also weak intramolecular C—H⋯Cl hydrogen bonds. According to the IR spectrum, solvent water was present in the crystal, but owing to the high thermal motion of the uncoordinated O atom, the H atoms could not be detected.

To a solution of K2PtCl6 (0.3002 g, 0.618 mmol) in H2O (20 ml) was added 1,10-phenanthroline (0.1108 g, 0.615 mmol) in MeOH (10 ml), and stirred for 3 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 (0.1655 g). Crystals suitable for X-ray analysis were obtained by slow evaporation from a CH2Cl2 solution. IR (KBr): 3424 cm-1 (broad).
H atoms were positioned geometrically and allowed to ride on their respective parent atoms [C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C)]. Due to the high thermal motion of the oxygen atom of the solvent H2O molecule, the H atoms could neither be located from Fourier difference maps, nor added geometrically.

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, [PtCl4(C12H8N2)].H2O, contains a neutral PtIV complex and a water molecule (Fig. 1 and 2). In the complex, the 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 contribution to the distortion is the tight N1—Pt1—N2 chelate angle (80.1 (2)°), which result in non-linear trans axes (<Cl1—Pt1—N1 = 174.0 (2)°, <Cl2—Pt1—N2 = 173.9 (2)° and <Cl3—Pt1—Cl4 = 176.84 (10)°). As a result of the different trans effects of the N and Cl atoms, the Pt—Cl bonds trans to the N atom (lengths: 2.317 (3) and 2.320 (2) Å) are slightly shorter than bond lengths to mutually trans Cl atoms (lengths: 2.343 (3) and 2.335 (3) Å). The compound displays intermolecular π-π interactions between six-membered rings, with a shortest centroid-centroid distance of 3.834 Å and with a dihedral angle between the ring planes of 1.48°. There are also weak intramolecular C—H···Cl hydrogen bonds (Table 1). According to the IR spectrum, water was present in the crystal.
