| Abstract: | The bis(2-amino-5-methylpyridinium) tetrabromomercurate(II) (C6H9N2)2HgBr4] salt is triclinic, P1, with the following cell parameters: a=8.060(8) ?, b=9.035(9) ?, c=14.964(10) ?, α=96.032(19)°, β=90.317(15)°, γ=113.32(2)°, V=993.8(15) ?3, with Z=2 formula units. The crystal structure consists of alternating stacks of inorganic HgBr4
2− anions and organic layers of 2-amino-5-methylpyridinium cations parallel to c-axis. The cohesion forces that connect molecules in the organic layers are N···HC hydrogen bonding and π–π stacking. The HgBr4
2− units in the inorganic stacks are attracted via Br···Br intermolecular interactions.Supplementary material CCDC 270395 contains the supplementary crystallographic data.
