Materials Data on SiSb3 by Materials Project
SiSb3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Si4+ is bonded in a 12-coordinate geometry to twelve equivalent Sb+1.33- atoms. There are six shorter (3.23 Å) and six longer (3.30 Å) Si–Sb bond lengths. Sb+1.33- is bonded in a 12-coordinate geometry to four equivalent Si4+ and eight equivalent Sb+1.33- atoms. There are a spread of Sb–Sb bond distances ranging from 3.07–3.40 Å.
