BaSi2O2N2 crystallizes in the orthorhombic Pbcn space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent N(1) and eight equivalent O(1) atoms. Si(1) is bonded to three equivalent N(1) and one O(1) atom to form corner-sharing SiN3O tetrahedra. N(1) is bonded in a trigonal planar geometry to one Ba(1) and three equivalent Si(1) atoms. O(1) is bonded in a distorted single-bond geometry to four equivalent Ba(1) and one Si(1) atom.
BaSi2O2N2 crystallizes in the orthorhombic Pbcn space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent N(1) and eight equivalent O(1) atoms. Both Ba(1)-N(1) bond lengths are 3.33 Å. There are a spread of Ba(1)-O(1) bond distances ranging from 2.79-3.09 Å. Si(1) is bonded to three equivalent N(1) and one O(1) atom to form corner-sharing SiN3O tetrahedra. There is one shorter (1.75 Å) and two longer (1.76 Å) Si(1)-N(1) bond lengths. The Si(1)-O(1) bond length is 1.63 Å. N(1) is bonded in a trigonal planar geometry to one Ba(1) and three equivalent Si(1) atoms. O(1) is bonded in a distorted single-bond geometry to four equivalent Ba(1) and one Si(1) atom.
