1,2,4,5-Tetrafluoro-3,6-diiodobenzene–2,3-bis(pyridin-2-yl)pyrazine (1/1)

The components of the title 1:1 co-crystal, C14H10N4·C6F4I2, are connected via an N...I [2.959 (4) Å] halogen bond, in which the N atom is part of the relatively electron-rich pyrazine ring. The C6F4I2 molecule is almost planar [r.m.s. deviation...
