The structure described by NaZnAs(H2O3)2 crystallizes in the triclinic P-1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded to two equivalent H(4), two equivalent O(3), two equivalent O(5), and two equivalent O(6) atoms to form distorted NaH2O6 hexagonal bipyramids that share corners with two equivalent Zn(1)O4 tetrahedra and corners with two equivalent As(1)O4 tetrahedra. In the second Na site, Na(2) is bonded in a 10-coordinate geometry to two equivalent H(1), two equivalent H(4), two equivalent O(4), two equivalent O(5), and two equivalent O(6) atoms. Zn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form ZnO4 tetrahedra that share  a cornercorner with one Na(1)H2O6 hexagonal bipyramid and corners with four equivalent As(1)O4 tetrahedra. As(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form AsO4 tetrahedra that share  a cornercorner with one Na(1)H2O6 hexagonal bipyramid and corners with four equivalent Zn(1)O4 tetrahedra. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one Na(2) and one O(5) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(5) atom. In the third H site, H(3) is bonded in a distorted linear geometry to one O(4) and one O(6) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one Na(1), one Na(2), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one As(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Zn(1) and one As(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Na(1), one Zn(1), and one As(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one Na(2), one Zn(1), one As(1), and one H(3) atom. In the fifth O site, O(5) is bonded in a distorted water-like geometry to one Na(1), one Na(2), one H(1), and one H(2) atom. In the sixth O site, O(6) is bonded in a water-like geometry to one Na(1), one Na(2), one H(3), and one H(4) atom. is represented by the CIF file [CIF]
