KKLiLa4O7 crystallizes in the trigonal P3 space group. The structure consists of one 7440-09-7 atom inside a KLiLa4O7 framework. In the KLiLa4O7 framework, K(2) is bonded in a 3-coordinate geometry to three equivalent O(2) atoms. Li(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent O(1) atoms. There are four inequivalent La sites. In the first La site, La(1) is bonded to one O(3) and three equivalent O(1) atoms to form LaO4 tetrahedra that share corners with three equivalent La(3)O6 octahedra, corners with three equivalent La(4)O6 octahedra, and  a cornercorner with one La(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 53-62°. In the second La site, La(2) is bonded to one O(3) and three equivalent O(2) atoms to form LaO4 tetrahedra that share corners with three equivalent La(3)O6 octahedra, corners with three equivalent La(4)O6 octahedra, and  a cornercorner with one La(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 57-60°. In the third La site, La(3) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form LaO6 octahedra that share corners with three equivalent La(1)O4 tetrahedra, corners with three equivalent La(2)O4 tetrahedra, and edges with three equivalent La(4)O6 octahedra. In the fourth La site, La(4) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form distorted LaO6 octahedra that share corners with three equivalent La(1)O4 tetrahedra, corners with three equivalent La(2)O4 tetrahedra, and edges with three equivalent La(3)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Li(1), one La(1), one La(3), and one La(4) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one K(2), one La(2), one La(3), and one La(4) atom. In the third O site, O(3) is bonded in a linear geometry to one La(1) and one La(2) atom.
