title: A twinned triclinic polymorph of dibromidotetrakis(tetrahydrofuran-kappaO)magnesium(II).
abstract: The title compound, [MgBr(2)(C(4)H(8)O)(4)], forms crystals which appear to be monoclinic but are actually twinned triclinic. The current form is a new triclinic polymorph, with Z'= 2, in addition to the already known tetragonal polymorph. Although the geometric parameters of the two polymorphs agree well, their packing patterns are completely different.
