The title dinuclear complex molecule, [Cu2(C13H9N4)2(PF6)2], lies about an inversion center. The CuII atom shows a square-pyramidal coordination geometry with the basal plane formed by four N atoms of the two bis-chelating 3,5-bis(pyridin-2-yl)pyrazolate ions and with one F atom of the hexafluorophosphate ion in the apical position. Molecules are stacked in a column along the a axis through C—H⋯F hydrogen bonds. The columns are further linked by other C—H⋯F hydrogen bonds, forming a three-dimensional network.

A methanolic solution of Cu(AcO)2.H2O (5ml, 20 mmol dm-3 ) was transferred to a glass tube, and then a methanolic solution of Hbpypz (5ml, 20 mmol dm-3), NaPF6 (5 ml, 10 mmol dm-3) were poured into the glass tube without mixing the solutions. Purple crystals began to format ambient temperature within one week. Yield: 14 mg (54 %). Elemental analysis (%) calcd for C26H18N8F12P2Cu2 : C 36.33, H 2.11, N 13.04; found: C 36.29, H 2.13, N 13.04.
The C-bound hydrogen atoms in the bpypz- ion were placed at calculated positions (C—H = 0.95 Å) and were treated as riding on their parent atoms with Uiso(H) = 1.2Ueq(C).

Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F2. R-factor (gt) are based on F. The threshold expression of F2 > 2.0 sigma(F2) is used only for calculating R-factor (gt). |

3,5-Bis(2-pyridyl)pyrazole [Hbpypz] can be used to construct of a series of mononuclear, dinuclear and polynuclear complexes as it is well-known due to the versatile properties of the ligand (Klingele et al., 2009). The Hbpypz has four N donors by deprotonation; the two N atoms in a pyrazole moiety and two N atoms in pyridine moieties. This ligand can bind to metal ions by behaving as a bidentate or as a tetradentate ligand and would be possible to form various coordination modes (Yoneda, Adachi, Hayami et al., 2006; Yoneda, Adachi, Nishio et al., 2006). In particular, two bpypz- ions form a planar dinuclear complex by chelating two metal ions at equatorial position (Washizaki et al., 2012). The dinuclear complex has unique coordination sites at the apical positions, which can trap ions hardly to coordinate. We have previously reported the dinuclear complex with coordinated hydrogensulfate ions at the apical sites (Mishima et al., 2011). The complex consists of a planer dinuclear complex and two hydrogensulfate ions, and forms a 1D chain with methanol molecules by hydrogen-bonding interactions.
The title planer dinuclear CuII complex with two PF6- ions has a similar structure to the above complex. The basal plane in the complex is formed by four N donors of two deprotnated tetradentate bridging bpypz- ligands. Cu—N distances are Cu—N1 2.0698 (15) Å, Cu—N2 1.9393 (16) Å, Cu—N3 1.9405 (15) Å, and Cu—N4 2.0577 (17) Å. CuII ions are each penta-coordinated by occupying PF6- ion at apical positions in the opposite direction and form a near ideal square-pyramidal coordination environment with t value of 0.068. The distance of Cu—F1 is 2.4027 (14) Å. To the best of our knowledge, the crystal structure report of PF6- coordinated CuII complex is only a few examples (Noro et al., 2011). The adjacent dinuclear complexes are stacked in columns through a weak π–π stacking interaction between pyridyl and pyrazol rings of the bpypz- ions (centroid-centroid distance 3.879 Å) and C—H···F hydrogen bonds between the bpypz- and the PF6- ions (Table 2). The C—H···F interactions are expected to be weak because of the low acidity of C—H system. However, the interatomic distances are in close contact; the distances of C—H···F bond are H1···F3 2.689 Å, H2···F4 2.666 Å, H8···F5 2.603 Å and H9···F3 2.522 Å. The supramolecular structure results from C—H···F bonds between adjacent columns. The distances between the columns are H3···F3 2.308 Å, H7···F2 2.536 Å and H5···F8 2.634 Å.
