The structure described by K3Ag3As2 crystallizes in the trigonal R-3m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 10-coordinate geometry to three equivalent K(2), six equivalent Ag(1), and four equivalent As(1) atoms. In the second K site, K(2) is bonded in a 18-coordinate geometry to six equivalent K(1), six equivalent Ag(1), and six equivalent As(1) atoms. Ag(1) is bonded in a distorted linear geometry to two equivalent K(2), four equivalent K(1), and two equivalent As(1) atoms. As(1) is bonded in a 10-coordinate geometry to three equivalent K(2), four equivalent K(1), and three equivalent Ag(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
