Materials Data on BaLi2Si by Materials Project
BaLi2Si crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. Li1+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. There are one shorter (2.69 Å) and two longer (2.78 Å) Li–Si bond lengths. Ba2+ is bonded to four equivalent Si4- atoms to form a mixture of distorted edge and corner-sharing BaSi4 tetrahedra. There are two shorter (3.46 Å) and two longer (3.61 Å) Ba–Si bond lengths. Si4- is bonded in a 10-coordinate geometry to six equivalent Li1+ and four equivalent Ba2+ atoms.
