The structure described by KBi(WO4)2 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 10-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(4), and four equivalent O(3) atoms. W(1) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form WO6 octahedra that share corners with two equivalent W(1)O6 octahedra, corners with four equivalent Bi(1)O6 pentagonal pyramids, and  an edgeedge with one W(1)O6 octahedra. The corner-sharing octahedral tilt angles are 37°. Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form distorted BiO6 pentagonal pyramids that share corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 28-66°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one W(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one K(1), one W(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded to one K(1), two equivalent W(1), and one Bi(1) atom to form a mixture of distorted corner and edge-sharing OKBiW2 tetrahedra. is represented by the CIF card [CIF]
