Materials Data on BaSiC by Materials Project
BaSiC crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Ba2+ is bonded in a 5-coordinate geometry to five equivalent Si4- atoms. There are one shorter (3.42 Å) and four longer (3.47 Å) Ba–Si bond lengths. Si4- is bonded in a single-bond geometry to five equivalent Ba2+ and one C2+ atom. The Si–C bond length is 1.71 Å. C2+ is bonded in a single-bond geometry to one Si4- atom.
