NaCo2(MoO5)2 crystallizes in the monoclinic C2/m space group. Na(1) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form distorted NaO6 octahedra that share corners with four equivalent Co(1)O6 octahedra and corners with six equivalent Mo(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 59°. Mo(1) is bonded to one O(3), one O(4), and two equivalent O(2) atoms to form MoO4 tetrahedra that share corners with three equivalent Na(1)O6 octahedra and corners with four equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-66°. Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form CoO6 octahedra that share corners with two equivalent Na(1)O6 octahedra, corners with four equivalent Mo(1)O4 tetrahedra, and edges with two equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles are 59°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to two equivalent Co(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to one Na(1), one Mo(1), and one Co(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Na(1) and one Mo(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Mo(1) and two equivalent Co(1) atoms.
