A structural study by means of X‐ray and electron diffraction of intermediate oxides between Eu 2 Mo 3 O 12 and Eu 2 W 3 O 12 shows the existence of a new Eu 2 (Mo 1−x W x ) 3 O 12 solid solution with the scheelite structural type. The essential feature of the x = 1/3 and x = 2/3 compounds is the presence of isolated oxygen tetrahedra, in which, according to X‐ray and electron diffraction data, W and Mo are randomly distributed. Eu atoms occupy distorted square antiprisms sites.
