The structure described by K3Na crystallizes in the hexagonal P6_3/mmc space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 10-coordinate geometry to eight K(1,1,1) and two equivalent Na(1) atoms. In the second K site, K(1) is bonded in a 10-coordinate geometry to eight K(1,1) and two equivalent Na(1) atoms. In the third K site, K(1) is bonded in a 10-coordinate geometry to eight K(1,1,1) and two equivalent Na(1) atoms. Na(1) is bonded in a 6-coordinate geometry to six K(1,1) atoms. is represented by the CIF card [CIF]
