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.

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. All K(1)-K(2) bond lengths are 3.82 Å. All K(1)-Ag(1) bond lengths are 3.57 Å. There is one shorter (3.31 Å) and three longer (3.46 Å) K(1)-As(1) bond lengths. 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. All K(2)-Ag(1) bond lengths are 3.97 Å. All K(2)-As(1) bond lengths are 3.85 Å. Ag(1) is bonded in a distorted linear geometry to two equivalent K(2), four equivalent K(1), and two equivalent As(1) atoms. Both Ag(1)-As(1) bond lengths are 2.56 Å. As(1) is bonded in a 10-coordinate geometry to three equivalent K(2), four equivalent K(1), and three equivalent Ag(1) atoms.
