The basic structure units are isolated polyhedral clusters composed of a central CrO<jats:sub>6<\/jats:sub>octahedron sharing vertices with six MoO<jats:sub>4<\/jats:sub>tetrahedra to form an open framework in which the Na<jats:sup>+<\/jats:sup>cations are bound to the free vertices of the MoO<jats:sub>4<\/jats:sub>tetrahedra. The Cr<jats:sup>3+<\/jats:sup>cation has site symmetry of 32 (6<jats:italic>a<\/jats:italic>), one Na atom sits on a twofold axis (18<jats:italic>e<\/jats:italic>), and all other atoms are at general positions. The bond-valance-sum model confirms the expected values of ion charges. The title compound is isotypic with Na<jats:sub>9<\/jats:sub>Sc(MoO<jats:sub>4<\/jats:sub>)<jats:sub>6<\/jats:sub>and Na<jats:sub>9<\/jats:sub>Fe(MoO<jats:sub>4<\/jats:sub>)<jats:sub>6<\/jats:sub>.
