The structure described by (KLa)(CaW)O6 is Orthorhombic Perovskite-derived structured and crystallizes in the orthorhombic Pnnn space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to four equivalent O(2) and four equivalent O(3) atoms. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. In the second Ca site, Ca(2) is bonded to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms to form CaO12 cuboctahedra that share faces with four equivalent La(1)O6 octahedra and faces with four equivalent W(1)O6 octahedra. La(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form LaO6 octahedra that share corners with six equivalent W(1)O6 octahedra and faces with two equivalent Ca(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 21-29°. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form WO6 octahedra that share corners with six equivalent La(1)O6 octahedra and faces with two equivalent Ca(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 21-29°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one Ca(1), one Ca(2), one La(1), and one W(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one K(1), one K(2), one Ca(2), one La(1), and one W(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one K(2), one Ca(2), one La(1), and one W(1) atom. is represented by the CIF card [CIF]
