The title complex, [N(CH3)(3)(C6H5)](4)[Cu6Br10], contains a centrosym
metric eight-membered ring of alternating Cu and Br atoms fused to two
six-membered rings of alternating Cu and Br atoms. The average Cu-Br
bond length is 2.377(4) Angstrom. A terminal Br atom is attached to on
e Cu atom of each of the six-membered rings [Cu-Br 2.290 (4) Angstrom]
. Two close Cu...Cu contacts [2.664(4) and 2.706(4) Angstrom] exist in
each six-membered ring.
