BaZn(SeO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ba2+ is bonded to six O2- atoms to form distorted BaO6 octahedra that share corners with two equivalent BaO6 octahedra and corners with three equivalent ZnO4 trigonal pyramids. The corner-sharing octahedral tilt angles are 58°. There are a spread of Ba–O bond distances ranging from 2.65–2.98 Å. Zn2+ is bonded to four O2- atoms to form distorted ZnO4 trigonal pyramids that share corners with three equivalent BaO6 octahedra. The corner-sharing octahedra tilt angles range from 41–64°. There are a spread of Zn–O bond distances ranging from 1.90–2.09 Å. There are two inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.67–2.12 Å. In the second Se4+ site, Se4+ is bonded in a water-like geometry to two O2- atoms. There is one shorter (1.76 Å) and one longer (1.82 Å) Se–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+, one Zn2+, and one Se4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+, one Zn2+, and one O2- atom. The O–O bond length is 1.45 Å. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+, one Zn2+, and one Se4+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Ba2+ and one Se4+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ba2+ and one Se4+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Zn2+, one Se4+, and one O2- atom.
