The crystal structure described by AcLa3 is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Ac(1) is bonded to twelve La(1,1,1) atoms to form AcLa12 cuboctahedra that share corners with six equivalent Ac(1)La12 cuboctahedra; corners with twelve La(1,1,1)Ac4La8 cuboctahedra; edges with eighteen La(1,1,1)Ac4La8 cuboctahedra; faces with eight equivalent Ac(1)La12 cuboctahedra; and faces with twelve La(1,1,1)Ac4La8 cuboctahedra. There are three inequivalent La sites. In the first La site, La(1) is bonded to four equivalent Ac(1) and eight La(1,1) atoms to form LaAc4La8 cuboctahedra that share corners with four equivalent Ac(1)La12 cuboctahedra; corners with fourteen equivalent La(1)Ac4La8 cuboctahedra; edges with six equivalent Ac(1)La12 cuboctahedra; edges with twelve La(1,1)Ac4La8 cuboctahedra; faces with four equivalent Ac(1)La12 cuboctahedra; and faces with sixteen La(1,1,1)Ac4La8 cuboctahedra.
