The compound described by Li(LaNb4O12)2 crystallizes in the orthorhombic Cmmm space group. The structure consists of two 7439-93-2 atoms inside a LaNb4O12 framework. In the LaNb4O12 framework, La(1,2) is bonded to four equivalent O(1,4); four equivalent O(2,3); and four equivalent O(5) atoms to form LaO12 cuboctahedra that share corners with four equivalent La(1,2)O12 cuboctahedra and faces with eight equivalent Nb(1)O6 octahedra. Nb(1) is bonded to one O(5); one O(6); two equivalent O(1,4); and two equivalent O(2,3) atoms to form NbO6 octahedra that share corners with six equivalent Nb(1)O6 octahedra and faces with two equivalent La(1,2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 1-14°. There are four inequivalent O sites. In the first O site, O(5) is bonded in a distorted linear geometry to two equivalent La(1,2) and two equivalent Nb(1) atoms. In the second O site, O(6) is bonded in a linear geometry to two equivalent Nb(1) atoms. In the third O site, O(1,4) is bonded in a distorted T-shaped geometry to one La(1,2) and two equivalent Nb(1) atoms. In the fourth O site, O(2,3) is bonded in a 2-coordinate geometry to one La(1,2) and two equivalent Nb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
