The crystal structure described by AcZn3 crystallizes in the hexagonal P6_3/mmc space group. Ac(1) is bonded in a 12-coordinate geometry to twelve equivalent Zn(1) atoms. Zn(1) is bonded in a 10-coordinate geometry to four equivalent Ac(1) and six equivalent Zn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
