The asymmetric unit of the title compound, [PtCl4(C12H12N2)], contains one half-mol­ecule; a twofold rotation axis passes through the Pt atom and the mid-point of the C—C bond linking the two rings. The PtIV atom is six-coordinated in an octa­hedral configuration by two N atoms of the 4,4′-dimethyl-2,2′-bipyridine ligand and four terminal Cl atoms. In the crystal structure, there are weak ππ inter­actions between pyridine rings, with a centroid–centroid distance of 4.365 (3) Å.

Amine platinum(IV) complexes have been known since the end of the last century (Hedin, 1886; Joergensen, 1900). Some of them have cancerostatic properties from which new interest aroused in these complexes (Bajusz et al., 1989; Vorobevdesyatovskii et al., 1991). Due to the kinetic inertness of hexachloro -platinate(IV), cis- and trans-[PtC14L2] complexes (L=N, O, P, S donor ligand) were mainly prepared by oxidation reactions of the corresponding platinum(II) complexes [PtCl2L2] (Hedin, 1886; Joergensen, 1900).

Several PtIV complexes, with formula, [PtCl4(N-N)], such as [PtCl4- (bipyi)], (II), (Gaballa et al., 2003), [PtCl4(Me2bim)], (III), (Casas et al., 2005), [PtCl4(bipy)], (IV), (Hambley, 1986), [PtCl4(dcbipy)].H2O, (V), (Hafizovic et al., 2006), [PtCl4{pz(py)2}], (VI), (Delir Kheirollahi Nezhad et al., 2008) and [PtCl4(dpk)], (VII), (Crowder et al., 2004) [where bipyi is 2,2'-bi-pyrimidinyl, Me2bim is 1,1'-dimethyl- 2,2'-bi-imidazolyl, bipy is 2,2'-bipyridine, dcbipy is 2,2'- bipyridine-5,5'-dicarboxylic acid, pz(py)2 is 2,3-bis(2-pyridyl)pyrazine and dpk is bis(2-pyridyl)ketone] have been synthesized and characterized by single-crystal X-ray diffraction methods.

There are also several PtIV complexes, with formula, [PtCl4L2], such as cis- and trans-[PtCl4(py)2], (VIII), (Junicke et al., 1997), cis- and trans-[PtCl4(PzH)2], (IX), (Khripun et al., 2006), trans-[PtCl4(NH3)2](1-Mu), (X), (Witkowski et al., 1997), trans-[PtCl4(1-Prim)2], (XI), (Kuduk-Jaworska et al., 1988), cis-[PtCl4(1-Etim)2], (XII), (Kuduk-Jaworska et al., 1990), trans-[PtCl4{NH=C(NMe2)OH}2], (XIII), (Bokach et al., 2003), trans-[PtCl4{NH=C(Me)ON=CMe2}2], (XIV), (Kukushkin et al., 1998), cis-[PtCl4{NH=C(Et)N=CPh2}2], (XV), (Garnovskii et al., 2001), trans- [PtCl4{NH=C(Et)ON=C(OH)Ph}2].2DMSO, (XVI), (Luzyanin, Kukushkin et al., 2002), trans-[PtCl4{NH=C(OMe)But}2], (XVII), (Gonzalez et al., 2002), trans-[PtCl4{NH=C(OH)Et}2], (XVIII), (Luzyanin, Haukka et al., 2002) and trans- [PtCl4(pz)2], (XIX), (Yousefi et al., 2007) [where PzH is pyrazole, 1-Mu is 1-methyluracil, 1-Prim is 1-propylimidazole, 1-Etim is 1-ethylimidazoyl and Pz is pyrazine] have been synthesized and characterized by single-crystal X-ray diffraction methods. We report herein the synthesis and crystal structure of the title compound, (I).

The asymmetric unit of (I) (Fig. 1) contains one-half molecule. The PtIV atom is six-coordinated in octahedral configuration (Table 1) by two N atoms of 4,4'-dimethyl-2,2'-bipyridine ligand and four terminal Cl atoms. The Pt-Cl and Pt-N bond lengths and angles (Table 1) are in good agreement with the corresponding values in (II), (III), (V) and (VI).

In the crystal structure, weak ππ interactions between pyridine rings [symmetry code: 3/2 - x, 1/2 - y, z] may be effective in the stabilization of the structure, with a centroid-centroid distance of 4.365 (3) Å.

Experimental top

For the preparation of the title compound, a solution of 4,4'-dimethyl-2,2' -bipyridine (0.11 g, 0.58 mmol) in methanol (10 ml) was added to a solution of H2PtCl6.6H2O, (0.30 g, 0.58 mmol) in methanol (10 ml) at room temperature. Crystals suitable for X-ray analysis were obtained by methanol diffusion in a solution of yellow precipitate in DMSO after one week (yield; 0.25 g, 82.8%).

Refinement top

H atoms were positioned geometrically, with C-H = 0.93 and 0.96 Å for aromatic and methyl H and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(C).

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 > 2sigma(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.
