Structure and magnetic properties of (5BAP)2CuBr4

The planes of pyridine rings are tilted approximately 67.9° with respect to the copper planes, resulting in a separation of copper centers in neighboring planes of 8.06 Å. Weak hydrogen bonding between the pyridinium hydrogen (H1) and Br1 (refer to Fig. 1, d N1 H1⋯Br1 =3.323(4) Å, angle=166(3)°) helps to stabilize the structure.
