Materials Data on Ba(AlSi)2 by Materials Project
BaAl2Si2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ba2+ is bonded in a 6-coordinate geometry to six equivalent Si4- atoms. There are two shorter (3.32 Å) and four longer (3.39 Å) Ba–Si bond lengths. Al3+ is bonded in a T-shaped geometry to three equivalent Si4- atoms. There are two shorter (2.54 Å) and one longer (2.58 Å) Al–Si bond lengths. Si4- is bonded in a 7-coordinate geometry to three equivalent Ba2+, three equivalent Al3+, and one Si4- atom. The Si–Si bond length is 2.41 Å.
