CaSnN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Ca(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CaN4 tetrahedra that share corners with four equivalent Ca(1)N4 tetrahedra and corners with eight equivalent Sn(1)N4 tetrahedra. Sn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form SnN4 tetrahedra that share corners with four equivalent Sn(1)N4 tetrahedra and corners with eight equivalent Ca(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Ca(1) and two equivalent Sn(1) atoms to form corner-sharing NCa2Sn2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Ca(1) and two equivalent Sn(1) atoms to form distorted corner-sharing NCa2Sn2 tetrahedra.
CaSnN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Ca(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CaN4 tetrahedra that share corners with four equivalent Ca(1)N4 tetrahedra and corners with eight equivalent Sn(1)N4 tetrahedra. Both Ca(1)-N(1) bond lengths are 2.36 Å. There is one shorter (2.40 Å) and one longer (2.43 Å) Ca(1)-N(2) bond length. Sn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form SnN4 tetrahedra that share corners with four equivalent Sn(1)N4 tetrahedra and corners with eight equivalent Ca(1)N4 tetrahedra. There is one shorter (2.06 Å) and one longer (2.08 Å) Sn(1)-N(1) bond length. There is one shorter (2.08 Å) and one longer (2.09 Å) Sn(1)-N(2) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Ca(1) and two equivalent Sn(1) atoms to form corner-sharing NCa2Sn2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Ca(1) and two equivalent Sn(1) atoms to form distorted corner-sharing NCa2Sn2 tetrahedra.
