The material structure described by KSmV4O12 crystallizes in the orthorhombic Amm2 space group. K(1) is bonded in a 10-coordinate geometry to two equivalent O(3), four equivalent O(1), and four equivalent O(4) atoms. Sm(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(5), and four equivalent O(1) atoms. V(1) is bonded to one O(1), one O(2), one O(3), one O(4), and one O(5) atom to form distorted corner-sharing VO5 trigonal bipyramids. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one K(1), one Sm(1), and one V(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Sm(1) and two equivalent V(1) atoms. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one K(1) and two equivalent V(1) atoms. In the fourth O site, O(4) is bonded in a distorted linear geometry to two equivalent K(1) and two equivalent V(1) atoms. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Sm(1) and two equivalent V(1) atoms. is represented by the CIF card [CIF]
