The material structure described by Na4ZnIn(PO4)3 crystallizes in the trigonal R3c space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Na site, Na(2) is bonded in a 6-coordinate geometry to three equivalent O(3) and three equivalent O(4) atoms. 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 P(1)O4 tetrahedra. In(1) is bonded to three equivalent O(2) and three equivalent O(4) atoms to form InO6 octahedra that share corners with six equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with two equivalent Zn(1)O6 octahedra and corners with two equivalent In(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 32-38°. There are four inequivalent O sites. In the first O site, O(3) is bonded to one Na(2), two equivalent Na(1), one Zn(1), and one P(1) atom to form distorted ONa3ZnP trigonal bipyramids that share corners with six equivalent O(4)Na3InP trigonal bipyramids,  an edgeedge with one O(4)Na3InP trigonal bipyramid, and faces with two equivalent O(3)Na3ZnP trigonal bipyramids. In the second O site, O(4) is bonded to one Na(2), two equivalent Na(1), one In(1), and one P(1) atom to form distorted ONa3InP trigonal bipyramids that share corners with six equivalent O(3)Na3ZnP trigonal bipyramids,  an edgeedge with one O(3)Na3ZnP trigonal bipyramid, and faces with two equivalent O(4)Na3InP trigonal bipyramids. In the third O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Na(1), one Zn(1), and one P(1) atom. In the fourth O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Na(1), one In(1), and one P(1) atom. is represented by the CIF card [CIF]
