BaZn2Sb2 crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 8-coordinate geometry to one Zn(1), three equivalent Sb(1), and four equivalent Sb(2) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one Ba(1), one Sb(1), and three equivalent Sb(2) atoms to form distorted ZnBaSb4 tetrahedra that share corners with two equivalent Zn(1)BaSb4 tetrahedra, corners with six equivalent Zn(2)Sb4 tetrahedra, and edges with two equivalent Zn(1)BaSb4 tetrahedra. In the second Zn site, Zn(2) is bonded to one Sb(2) and three equivalent Sb(1) atoms to form distorted ZnSb4 tetrahedra that share corners with two equivalent Zn(2)Sb4 tetrahedra, corners with six equivalent Zn(1)BaSb4 tetrahedra, and edges with two equivalent Zn(2)Sb4 tetrahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 7-coordinate geometry to three equivalent Ba(1), one Zn(1), and three equivalent Zn(2) atoms. In the second Sb site, Sb(2) is bonded in a 8-coordinate geometry to four equivalent Ba(1), one Zn(2), and three equivalent Zn(1) atoms.
