Abstract
The crystal structures of [Ni(17-aneN5)H2O]Br2·3H2O (17-aneN5=1,4,7,11,14-pentaazacycloheptadecane) and of [Cu(17-aneN5)]CuBr4 are reported. Diffraction data using MoKα radiation were measured with a CAD-4 diffractometer and the structures refined by full-matrix least squares. The nickel compound has regular octahedral coordination with coordinated water completing the octahedron. The copper is approximately square-pyramidal with an apical Cu-N bond of 2.29(4) Å, compared to a mean bond length of 2.06(2) Å in the basal plane. As a result, the folding of the 17-membered macrocyclic rings is completely different in the two compounds.
