N2  - The crystal structure of the title compound, hexa-μ2-bromido-μ4-oxido-tetra­kis­[(diethyl ether)magnesium], [Mg4Br6O(C4H10O)4], determined from data measured at 173 K, differs from the previously known structure of diethyl ether magnesium oxybromide, which was determined from room-temperature data [Stucky & Rundle (1964 [triangle]). J. Am. Chem. Soc. 86, 4821–4825]. The title compound crystallizes in the tetra­gonal space group I An external file that holds a picture, illustration, etc. Object name is e-67-m1614-efi7.jpg, whereas the previously known structure crystallizes in a different tetra­gonal space group, namely P An external file that holds a picture, illustration, etc. Object name is e-67-m1614-efi7.jpg21 c. Both molecules have crystallographic An external file that holds a picture, illustration, etc. Object name is e-67-m1614-efi7.jpg symmetry and show almost identical geometric parameters for the Mg, Br and O atoms. The crystal of the title compound turned out to be a merohedral twin emulating a structure with apparent Laue symmetry 4/mmm, whereas the correct Laue group is just 4/m. The fractional contribution of the minor twin component converged to 0.462 (1).
