Abstract

NaAl(MoO4)2, sodium aluminium dimolybdate(VI), represents a rare pseudo-orthorhombic structure type among AM(XO 4)2 compounds with yavapaiite-related sheet structures. It is isostructural with NaFe(MoO4)2. Infinite (001) sheets composed of AlO6 octahedra, corner-linked to MoO4 tetrahedra, are separated by eight-coordinated Na atoms. Average Na-O, Al-O and Mo-O bond lengths are 2.648, 1.890, and 1.762 A°, respectively. All atoms are on general positions except for Na and Al (both of which have site symmetry 1¯).
