SrTaO2N is (Cubic) Perovskite-derived structured and crystallizes in the orthorhombic Pmm2 space group. Sr(1) is bonded to four equivalent N(1), four equivalent O(1), and four equivalent O(2) atoms to form SrN4O8 cuboctahedra that share corners with twelve equivalent Sr(1)N4O8 cuboctahedra, faces with six equivalent Sr(1)N4O8 cuboctahedra, and faces with eight equivalent Ta(1)N2O4 octahedra. Ta(1) is bonded to two equivalent N(1), two equivalent O(1), and two equivalent O(2) atoms to form TaN2O4 octahedra that share corners with six equivalent Ta(1)N2O4 octahedra and faces with eight equivalent Sr(1)N4O8 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-7°. N(1) is bonded to four equivalent Sr(1) and two equivalent Ta(1) atoms to form a mixture of distorted edge and corner-sharing NSr4Ta2 octahedra. The corner-sharing octahedral tilt angles range from 3-7°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent Sr(1) and two equivalent Ta(1) atoms. In the second O site, O(2) is bonded in a distorted linear geometry to four equivalent Sr(1) and two equivalent Ta(1) atoms.

There are two shorter (2.81 Å) and two longer (2.94 Å) Sr(1)-N(1) bond lengths. All Sr(1)-O(1) bond lengths are 2.89 Å. All Sr(1)-O(2) bond lengths are 2.88 Å. Ta(1) is bonded to two equivalent N(1), two equivalent O(1), and two equivalent O(2) atoms to form TaN2O4 octahedra that share corners with six equivalent Ta(1)N2O4 octahedra and faces with eight equivalent Sr(1)N4O8 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-7°. Both Ta(1)-N(1) bond lengths are 2.05 Å. Both Ta(1)-O(1) bond lengths are 2.03 Å. There is one shorter (1.98 Å) and one longer (2.09 Å) Ta(1)-O(2) bond length.
