Crystal structure of bis-(3-carb-oxy-1-methyl-pyrid-inium) octa-bromide.

ABSTRACT: The crystal structure of the title salt, bis-(3-carb-oxy-1-methyl-pyridinium) octa-bromide, 2C₇H₈NO₂ ⁺·Br₈ ^2-, consists of 3-carb-oxy-1-methyl-pyridinium (N-methyl-nicotinic acid) cations, which are stacked between relatively rare [Br₈]^2- anions. The polybromide [Br₈]^2- anion has point group symmetry and can be described as being composed of two [Br₃]^- anions connected with a Br₂ mol-ecule in a Z-shaped manner. Contacts between neighboring octa-bromide anions ensure the creation of pseudo-polymeric chains propagating along [111]. The organic cations are located between anionic chains and are connected to each other through O-H⋯O hydrog
