Bis-(2-amino-6-methyl-pyridinium) tetra-bromido-cuprate(II).

Bottom Line: Each [CuBr(4)](2-) anion is connected non-symmetrically to four surrounding cations through N-H⋯X (pyridine and amine proton) hydrogen bonds, forming chains of the ladder-type running parallel to the crystallographic b axis.These layers are further connected by means of offset face-to-face inter-actions (parallel to the a axis), giving a three-dimensional network.There are no inter-molecular Br⋯Br inter-actions.

ABSTRACT
In the crystal structure of the title compound, (C(6)H(9)N(2))(2)[CuBr(4)], the geometry around the Cu atom is inter-mediate between tetra-hedral (T(d)) and square planar (D(4h)). Each [CuBr(4)](2-) anion is connected non-symmetrically to four surrounding cations through N-H⋯X (pyridine and amine proton) hydrogen bonds, forming chains of the ladder-type running parallel to the crystallographic b axis. These layers are further connected by means of offset face-to-face inter-actions (parallel to the a axis), giving a three-dimensional network. Cation π-π stacking [centroid separations of 3.69 (9) and 3.71 (1) Å] and Br⋯aryl inter-actions [3.72 (2) and 4.04 (6) Å] are present in the crystal structure. There are no inter-molecular Br⋯Br inter-actions.
