The title compound, [Cu2(C13H9N4)2(HSO4)2]·2CH3OH, consists of discrete centrosymmetric dinuclear complex molecules and methanol solvent molecules. The CuII atom shows a square-pyramidal coordination geometry and is bonded to four N atoms of the two bis-chelating 3,5-bis(2-pyridyl)pyrazolate ions (bpypz−) and one O atom of the hydrogensulfate ion. The bpypz− ligands in the complex molecule are virtually coplanar [dihedral angle between the mean ligand planes = 0.000(1)°] with the CuII atom deviating in opposite directions from their best plane by 0.2080 (12) Å. π–π stacking interactions between the pyridyl and pyrazole rings [centroid–centroid distance = 3.391 (3) Å] and strong O—H⋯O hydrogen bonds between the hydrogensulfate ligands and the methanol molecules assemble the molecules into a one-dimensional polymeric structure extending along the a axis. The methanol molecule acts both as an accepter and a donor in the hydrogen bonding.

A methanolic solution of CuSO4.6H2O (5ml, 10 mmolL-1) was transferred to a glass tube, and then a methanolic solution of Hbpypz (5ml, 10 mmolL-1) was poured into the glass tube without mixing the solutions. Green crystals began to form at ambient temperature within one week (yield 84%). Elemental analysis: calcd (%) for C28H28Cu2N8O10S2: C 40.62, H 3.41, N 13.54; found: C 40.45, H 3.28, N 13.60.
The C-bound hydrogen atoms in the bpypz- ion and the methyl group of the methanol molecule were placed at calculated positions, C—H 0.950 Å and 0.980 Å respectively, and were treated as riding on their parent atoms with Uiso(H) set to 1.2 Ueq(C). The O-bound hydrogen atoms in the hydrogensulfate ion and the methanol molecule were located in a difference Fourier map. The H-atom coordinates were fixed. The distances were O2–H10 0.90 Å and O5–H11 0.96 Å.

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 σ(F2) is used only for calculating R-factor (gt). |

3,5-Bis(2-pyridyl)pyrazole[Hbpypz] is a versatile ligand in the construction of a series of mononuclear, dinuclear and polynuclear complexes (Munakata et al., 1995; Du et al., 2005; Yoneda et al., 2006; Ishikawa et al., 2010). The dinuclear complexes show the structure where two bpypz- ions are bridging two metal ions with the axial coordination sites. This kind of dinuclear complexes with transition metal ions were reported previously (Nakano et al., 2004; Yoneda et al., 2006; Ishikawa et al., 2008). The title compound consists of the CuII dinuclear complex and two methanol solvent molecules. In the dinuclear complex, four N donors from two deprotonated tetradentate bridging bpypz- ligands form the basal plane (Table 1). The copper(II) ion is penta-coordinated and it is in a slightly deformed square-pyramidal coordination environment with the τ value of 0.001 (Fig. 1). The apical position is occupied by the hydrogensulfate ion. An uncommon feature is that a sulfate ion is actually bound as the hydrogensulfate ion as there are only a few instances of unidentately coordinated hydrogensulfate ion (Dragancea et al., 2008). The π···π stacking interactions between pyridyl and pyrazole rings [centroid-centroid distance 3.391 (3) Å ] and strong hydrogen bonds between the hydrogensulfate ligands and the methanol molecules assemble molecules into a one dimensional polymeric structure extended along the a axis (Table 2, Fig. 2). The methanol molecule acts both as an accepter and a donor in O-H···O hydrogen bond.
