Crystal structure of Cr-bearing Mg3BeAl8O16, a new polytype of magnesiotaaffeite-2N′2S

The crystal structure of a new polytype of magnesiotaaffeite-2N′2S is described. The S (Mg2Al4O8) and N′ (BeMgAl4O8) modules have the stacking sequence NSSN''.

Two polymorphs of trans-[3-(3-nitro­phen­yl)oxiran-2-yl](phen­yl)methanone

The title compound, C15H11NO4, crystallizes in two polymorphic forms, centrosymmetric monoclinic and chiral ortho­rhom­bic. The geometry of the mol­ecules in the two polymorphs is slightly different, possibly due to inter­molecular inter­actions. A number of C—H⋯O inter­molecular inter­actions, involving both O atoms of the nitro as well the benzoyl groups, stabilize the crystal structures.
