A gadolinium and niobium oxide sulfide, Gd3NbS3O4

The structure of the title compound, trigadolinium niobium tri­sulfide tetraoxide, Gd3NbS3O4, was determined by single-crystal X-ray diffraction. Gd3NbS3O4 crystallizes in the non-centrosymmetric space group Pn21a (No.33) of the orthorhombic system. It is isostructural with Sm3NbS3O4.
