Materials Data on AcSi3 by Materials Project

AcSi3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ac is bonded to twelve equivalent Si atoms to form a mixture of distorted face and corner-sharing AcSi12 cuboctahedra. There are six shorter (3.28 Å) and six longer (3.29 Å) Ac–Si bond lengths. Si is bonded in a 10-coordinate geometry to four equivalent Ac and six equivalent Si atoms. There are two shorter (2.51 Å) and four longer (2.73 Å) Si–Si bond lengths.
