BaSi2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a distorted q4 geometry to ten equivalent Si(1) atoms. Si(1) is bonded in a 6-coordinate geometry to five equivalent Ba(1) and one Si(1) atom.
BaSi2 crystallizes in the tetragonal I4/mmm space group. Ba(1) is bonded in a distorted q4 geometry to ten equivalent Si(1) atoms. There are two shorter (3.36 Å) and eight longer (3.61 Å) Ba(1)-Si(1) bond lengths. Si(1) is bonded in a 6-coordinate geometry to five equivalent Ba(1) and one Si(1) atom. The Si(1)-Si(1) bond length is 2.17 Å.
