The compound described by KPb4(VO4)3 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(3), and three equivalent O(4) atoms. V(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form VO4 tetrahedra that share corners with four equivalent Pb(1)O6 pentagonal pyramids and  an edgeedge with one Pb(1)O6 pentagonal pyramid. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form distorted PbO6 pentagonal pyramids that share corners with four equivalent Pb(1)O6 pentagonal pyramids, corners with four equivalent V(1)O4 tetrahedra, and  an edgeedge with one V(1)O4 tetrahedra. In the second Pb site, Pb(2) is bonded in a 3-coordinate geometry to three equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded in a distorted single-bond geometry to one K(1), one V(1), one Pb(1), and one Pb(2) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to one K(1), one V(1), and two equivalent Pb(1) atoms. In the third O site, O(2) is bonded in a distorted single-bond geometry to one V(1) and two equivalent Pb(1) atoms. In the fourth O site, O(3) is bonded in a 3-coordinate geometry to one K(1), one V(1), and one Pb(1) atom. is represented by the CIF card [CIF]
