Materials Data on AcCu3 by Materials Project
AcCu3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ac is bonded in a 12-coordinate geometry to twelve equivalent Cu atoms. There are six shorter (3.21 Å) and six longer (3.37 Å) Ac–Cu bond lengths. Cu is bonded in a 10-coordinate geometry to four equivalent Ac and six equivalent Cu atoms. There are two shorter (2.51 Å) and four longer (2.58 Å) Cu–Cu bond lengths.
