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.

A mixture of 1,3-di(2'-pyrimidyl)-5-methoxybenzene 200 mg (0.756 mmol) and K2PtCl4 314 mg (0.756 mmol) in CH3CN/H2O (v/v, 1/1, 60 ml) was stirred under reflux for 24 h in an argon atmosphere (Cardenas & Echavarren,, 1999). The resulted red solution was evaporated and the residue was extracted with CH2Cl2. The title complex was separated by flash
(SiO2, CH2Cl2 as eluent) from the mixture. The single-crystal was obtained by slow evaporation of an acetonitrile solution of the title complex.All H atoms were placed geometrically and treated as riding on their parent atoms with C—H = 0.96 (methyl) Å [U iso (H) = 1.5U eq (C)], and C—H = 0.93 (aromatic) Å [U iso (H) = 1.2U eq (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 > 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. |

Square planar PtII complexes with tridentate cyclometalating NCN ligands [e.g., m-di(2-pyridinyl)benzene (dpb) derivatives (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). Recently, some PtII complex with novel tridentate NCN ligands have been reported (Tam et al., 2011; Kozhevnikov et al., 2008). In this point of view, we develop a novel tridentate NCN ligand (Avitia et al., 2011; Wakioka et al., 2010), 1,3-di(2'-pyrimidyl)-5-methoxybenzene. Interestingly, in an attempt to prepare square PtII complex by the reaction of K2PtCl4 with newly synthesized ligand, the neutral PtIV complex, [Pt(C15H11N4O)Cl3].CH3CN, was unexpected obtained as a byproduct along with the PtII complex, [Pt(C15H11N4O)Cl].
The asymmetric unit of the title compound, contains a neutral PtIV complex and one acetonitrile molecule (Fig. 1). The central platinum(IV) atom is coordinated by two nitrogen atoms and one carbon atom from tridentate ligand, and three chlorine atoms forming a distorted octahedral geometry. The angles C5—Pt1—Cl3, N3—Pt1—Cl3, N1—Pt1—Cl3, C5—Pt1—Cl2, Cl3—Pt1—Cl1, N3—Pt1—Cl2, N1—Pt1—Cl2 and Cl2—Pt1—Cl1 (88.14 (13)—92.288 (13)°, Table 1) are very close to the ideal 90°, the deviation from 90° of the angles C5—Pt1—N3 (80.3 (2)°) and C5—Pt1—N1 (80.7 (2)°) are owing to the formation of five-membered chelating rings. The bond lengths of Pt–N1, Pt–C5, Pt–N3, and Pt–Cl1 (Table 1) are similar to the literature reported Pt(II)dpbCl complexes (Wang et al., 2010). The bond lengths of Pt–Cl2 and Pt–Cl3 (Table 1) resemble those in other PtIV complexes, which have been published (Bagchi et al., 2007; Bokach et al., 2012). The title complex packed as head-to-tail dimers in the crystal, each molecular unit of the dimer related to the other by a center of inversion. They are further connected into three-dimension crystal structure via C—H···Cl hydrogen-bonding interactions and π–π stacking interactions between tridentate ligands, the shortest ring centroid-centroid distance is 3.613 Å (Table 2).
