The material described by NdMo8O14 crystallizes in the orthorhombic Aea2 space group. Nd(1) is bonded in a 7-coordinate geometry to one O(3), two equivalent O(4), two equivalent O(5), and two equivalent O(6) atoms. There are four inequivalent Mo sites.

The corner-sharing octahedral tilt angles range from 19-50°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Mo(1), one Mo(2), and one Mo(4) atom. In the second O site, O(2) is bonded in a see-saw-like geometry to two equivalent Mo(2) and two equivalent Mo(3) atoms.
