NaLaZn(SO4)3 crystallizes in the trigonal R3c space group. Na(1) is bonded in a 3-coordinate geometry to three equivalent O(3) atoms. La(1) is bonded to three equivalent O(2) and three equivalent O(4) atoms to form LaO6 octahedra that share corners with six equivalent S(1)O4 tetrahedra. Zn(1) is bonded to three equivalent O(1) and three equivalent O(3) atoms to form ZnO6 octahedra that share corners with six equivalent S(1)O4 tetrahedra. S(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SO4 tetrahedra that share corners with two equivalent La(1)O6 octahedra and corners with two equivalent Zn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-41°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Zn(1) and one S(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one La(1) and one S(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Na(1), one Zn(1), and one S(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one La(1) and one S(1) atom.
