NaMgSb is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Na(1) is bonded in a 5-coordinate geometry to five equivalent Sb(1) atoms. Mg(1) is bonded to four equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing MgSb4 tetrahedra. Sb(1) is bonded in a 9-coordinate geometry to five equivalent Na(1) and four equivalent Mg(1) atoms.
NaMgSb is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Na(1) is bonded in a 5-coordinate geometry to five equivalent Sb(1) atoms. There is one shorter (3.17 Å) and four longer (3.44 Å) Na(1)-Sb(1) bond lengths. Mg(1) is bonded to four equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing MgSb4 tetrahedra. All Mg(1)-Sb(1) bond lengths are 2.89 Å. Sb(1) is bonded in a 9-coordinate geometry to five equivalent Na(1) and four equivalent Mg(1) atoms.
