Materials Data on KAc3 by Materials Project

Abstract

KAc3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. K is bonded to twelve equivalent Ac atoms to form KAc12 cuboctahedra that share corners with twelve equivalent KAc12 cuboctahedra, edges with twenty-four equivalent AcK4Ac8 cuboctahedra, faces with six equivalent KAc12 cuboctahedra, and faces with twelve equivalent AcK4Ac8 cuboctahedra. All K–Ac bond lengths are 4.06 Å. Ac is bonded to four equivalent K and eight equivalent Ac atoms to form AcK4Ac8 cuboctahedra that share corners with twelve equivalent AcK4Ac8 cuboctahedra, edges with eight equivalent KAc12 cuboctahedra, edges with sixteen equivalent AcK4Ac8 cuboctahedra, faces with four equivalent KAc12 cuboctahedra, and faces with fourteen equivalent AcK4Ac8 cuboctahedra. All Ac–Ac bond lengths are 4.06 Å.
