FeSnN2 crystallizes in the orthorhombic Pna2_1 space group. Fe(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing FeN4 tetrahedra. Sn(1) is bonded in a distorted T-shaped geometry to one N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to two equivalent Fe(1) and one Sn(1) atom. In the second N site, N(2) is bonded to two equivalent Fe(1) and two equivalent Sn(1) atoms to form distorted corner-sharing NFe2Sn2 tetrahedra.
FeSnN2 crystallizes in the orthorhombic Pna2_1 space group. Fe(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing FeN4 tetrahedra. There is one shorter (1.78 Å) and one longer (1.79 Å) Fe(1)-N(1) bond length. There is one shorter (1.82 Å) and one longer (1.85 Å) Fe(1)-N(2) bond length. Sn(1) is bonded in a distorted T-shaped geometry to one N(1) and two equivalent N(2) atoms. The Sn(1)-N(1) bond length is 2.28 Å. There is one shorter (2.28 Å) and one longer (2.33 Å) Sn(1)-N(2) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to two equivalent Fe(1) and one Sn(1) atom. In the second N site, N(2) is bonded to two equivalent Fe(1) and two equivalent Sn(1) atoms to form distorted corner-sharing NFe2Sn2 tetrahedra.
