Ac3V is Uranium Silicide-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Ac sites. In the first Ac site, Ac(1) is bonded to four equivalent Ac(1), four equivalent Ac(2), and four equivalent V(1) atoms to form distorted AcAc8V4 cuboctahedra that share corners with twelve equivalent Ac(1)Ac8V4 cuboctahedra, edges with eight equivalent Ac(1)Ac8V4 cuboctahedra, edges with eight equivalent V(1)Ac12 cuboctahedra, faces with four equivalent V(1)Ac12 cuboctahedra, and faces with ten equivalent Ac(1)Ac8V4 cuboctahedra. In the second Ac site, Ac(2) is bonded in a distorted square co-planar geometry to eight equivalent Ac(1) and four equivalent V(1) atoms. V(1) is bonded to four equivalent Ac(2) and eight equivalent Ac(1) atoms to form VAc12 cuboctahedra that share corners with four equivalent V(1)Ac12 cuboctahedra, edges with eight equivalent V(1)Ac12 cuboctahedra, edges with sixteen equivalent Ac(1)Ac8V4 cuboctahedra, faces with four equivalent V(1)Ac12 cuboctahedra, and faces with eight equivalent Ac(1)Ac8V4 cuboctahedra.
