The compound described by La7Mo7O30 crystallizes in the trigonal R-3 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(3), two equivalent O(4), and two equivalent O(5) atoms. In the second La site, La(2) is bonded to six equivalent O(1) and six equivalent O(3) atoms to form LaO12 cuboctahedra that share faces with two equivalent Mo(2)O6 octahedra and faces with six equivalent Mo(1)O6 octahedra. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(1), one O(2), one O(4), one O(5), and two equivalent O(3) atoms to form distorted MoO6 octahedra that share  a cornercorner with one Mo(2)O6 octahedra, corners with two equivalent Mo(1)O6 octahedra, and  a faceface with one La(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 30-39°. In the second Mo site, Mo(2) is bonded to six equivalent O(1) atoms to form MoO6 octahedra that share corners with six equivalent Mo(1)O6 octahedra and faces with two equivalent La(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 39°. There are five inequivalent O sites. In the first O site, O(1) is bonded to one La(1), one La(2), one Mo(1), and one Mo(2) atom to form a mixture of distorted corner and edge-sharing OLa2Mo2 tetrahedra. In the second O site, O(2) is bonded in a 1-coordinate geometry to one La(1) and one Mo(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one La(1), one La(2), and two equivalent Mo(1) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent La(1) and one Mo(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to two equivalent La(1) and one Mo(1) atom. is represented by the CIF file [CIF]
