KMgSb is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. K(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 corner and edge-sharing MgSb4 tetrahedra. Sb(1) is bonded in a 9-coordinate geometry to five equivalent K(1) and four equivalent Mg(1) atoms.
KMgSb is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. K(1) is bonded in a 5-coordinate geometry to five equivalent Sb(1) atoms. There are four shorter (3.63 Å) and one longer (3.69 Å) K(1)-Sb(1) bond length. Mg(1) is bonded to four equivalent Sb(1) atoms to form a mixture of corner and edge-sharing MgSb4 tetrahedra. All Mg(1)-Sb(1) bond lengths are 2.92 Å. Sb(1) is bonded in a 9-coordinate geometry to five equivalent K(1) and four equivalent Mg(1) atoms.
