The compound described by KAs3(PbO3)4 crystallizes in the hexagonal P6_3 space group. K(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(4) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 6-coordinate geometry to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms. In the second Pb site, Pb(2) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. As(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(4) is bonded in a 3-coordinate geometry to one K(1), one Pb(1), and one As(1) atom. In the second O site, O(1) is bonded in a 1-coordinate geometry to one K(1), one Pb(1), one Pb(2), and one As(1) atom. In the third O site, O(2) is bonded in a distorted single-bond geometry to one K(1), two equivalent Pb(1), and one As(1) atom. In the fourth O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Pb(1) and one As(1) atom. is represented by the CIF file [CIF]
