The material structure described by MgNb2 crystallizes in the orthorhombic Fmmm space group. Mg(1) is bonded in a 12-coordinate geometry to four equivalent Mg(1) and eight equivalent Nb(1) atoms. Nb(1) is bonded in a 8-coordinate geometry to four equivalent Mg(1) and six equivalent Nb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
