Abstract
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.
