RESUMO
In the asymmetric unit of the title compound, [CuBr(C18H18N4)]Br, there are three crystallographically independent cations. One of the cations exhibits positional disorder of the pyridin-2-yl-methyl groups over two sets of sites with refined occupancies of 0.672â (8) and 0.328â (8). The outer-sphere bromine counter-ion is severely disordered over multiple sites. In each cation, the Cu(II) ion is coordinated by the four N atoms of the tris-(pyridin-2-ylmeth-yl)amine ligand and one bromine and adopts a slightly distorted trigonal-bipyramidal geometry.
