BaLi2Si crystallizes in the orthorhombic Pmmn space group. Li(1) is bonded in a distorted trigonal planar geometry to four equivalent Ba(1) and three equivalent Si(1) atoms. Ba(1) is bonded in a 12-coordinate geometry to eight equivalent Li(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to six equivalent Li(1) and four equivalent Ba(1) atoms.
BaLi2Si crystallizes in the orthorhombic Pmmn space group. Li(1) is bonded in a distorted trigonal planar geometry to four equivalent Ba(1) and three equivalent Si(1) atoms. There are a spread of Li(1)-Ba(1) bond distances ranging from 3.41-3.68 Å. There is one shorter (2.67 Å) and two longer (2.77 Å) Li(1)-Si(1) bond lengths. Ba(1) is bonded in a 12-coordinate geometry to eight equivalent Li(1) and four equivalent Si(1) atoms. There are two shorter (3.46 Å) and two longer (3.61 Å) Ba(1)-Si(1) bond lengths. Si(1) is bonded in a 10-coordinate geometry to six equivalent Li(1) and four equivalent Ba(1) atoms.
