【 摘 要 】

The structure of the title co-crystal, C24H16N6·4.75H2O2, consists of a 2,3,5,6-tetra­kis­(pyridin-2-yl)pyrazine coformer and hydrogen peroxide solvent mol­ecules in an overall ratio of 1:4.75. Three of the six H2O2 mol­ecules modelled in the structure were found to be cross-orientationally disordered over two positions with occupancy ratios 0.846 (9):0.154 (9), 0.75 (2):0.25 (2), and 0.891 (9):0.109 (9). In the crystal, all of the peroxide mol­ecules are linked into hydrogen-bonded chains that propagate parallel to the a axis. These chains are further linked by O—H⋯N hydrogen bonds to the pyridine groups of the main mol­ecule.
