The crystal structure of the title compound, [HgBr(C16H25O5)], shows a
nearly-linear geometry at the Hg atom [Cl-Hg-Br = 177.52(13)degrees],
and only weak interactions between the Hg atom and the O atoms in the
open-chain polyether ligand. The three shortest Hg ... O distances [2
.862 (4), 2.949 (4) and 3.010 (4) Angstrom], of which only one is intr
amolecular, are distinctly longer than in comparable ketones and carbo
xylates.
