In the title compound, [Pt(CH₃)₃I(C₁₂H₁₂N₂)], the Pt^IV atom is six-coordinated in a slightly distorted octahedral configuration with one CH₃ group and the I atom forming a near perpendicular axis relative to the square plane formed by the bipyridine ligand and the two remaining CH₃ groups. The CH₃ group trans to the I atom has a slightly elongated bond to Pt compared to the other CH₃ groups, indicating a difference in trans influence between iodine and the bipyridine ligand.

Comment top

As a part of a larger project, the title compound and several other compounds based on substituted bipyridines and Pt^IV salts were synthesized in an NMR-screening for new Pt^IV complexes for potential application in bimetallic MOFs (Metal-Organic Frameworks). Bimetallic MOFs containing bipyridine, Pt(II) (Szeto et al., 2006, 2008) and Pd(II) (Bloch et al., 2010) have previously been reported, but so far no thermally stable bimetallic MOF containing Pt^IV is reported in the literature.

The title compound has previously been reported (Clegg et al., 1972) as a part of an extensive NMR-studies to find evidence for cis and trans influences in trimethylplatinum(IV) compounds. The NMR spectra of the compound is in good accordance with what was reported, and the crystal structure supports the finds with regards to trans influences.

Experimental top

The title compound was synthesized by a modified version of the method used by Clegg et al. (1972). 5,5'-dimethyl-2,2'-bipyridine (1.2 mg, 0.006 mmol) and Pt^IV(CH₃)₃I (2.0 mg, 0,005 mmol) was weighed out in an NMR-tube, and 0.5 ml of deuterated benzene (C₆D₆) was added. The resulting mixture was heated to 75 °C for 3 days without stirring. A number of NMR-spectra were recorded during the synthesis to monitor the formation of the complex. After the NMR-experiments were finished, the NMR-tube was left at ambient temperature for 7 days, during which crystals of the complex formed.

Special details top

Experimental. Synthesis of the complex was performed in deuterated solvent.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
