Trichlorido[4-methoxy-2,6-bis(2-pyrimidin-2-yl-κN)phenyl-κC 1]platinum(IV) acetonitrile monosolvate

In the title complex, [Pt(C15H11N4O)Cl3]·CH3CN, the PtIV ion adopts a distorted octahedral coordination geometry defined by a tridentate cyclometalated NCN ligand and three Cl atoms. In the crystal, individual molecules are aggregated into a three-dimensional network by C—H⋯Cl hydrogen-bonding interactions and π–π stacking interactions between the tridentate ligands, the shortest ring centroid–centroid distance being 3.613 Å.

Experimental
Crystal data [Pt(C 15 Table 1 Selected bond lengths (Å ).   (Wang et al., 2010)] have attracted a great attention due to their potential application in wide ranges such as chemosensors, luminescent materials, as well as photovoltaic cells (Williams 2009;Chen et al., 2009;Lu et al., 2009).
The resulted red solution was evaporated and the residue was extracted with CH 2 Cl 2 . The title complex was separated by flash column chromatography (SiO 2 , CH 2 Cl 2 as eluent) from the mixture. The single-crystal was obtained by slow evaporation of an acetonitrile solution of the title complex.

Special details
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 F 2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F 2 , conventional R-factors R are based on F, with F set to zero for negative F 2 . The threshold expression of F 2 > σ(F 2 ) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F 2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
