Abstract
X-ray diffraction study of a new representative of the eudialyte family (R = 4.5%, 2347 independent reflections) provided the establishment of a numbe r of characteristic features of its structure associated with a high zircon ium content and some other characteristics of the composition. The deficien cy of Ca is compensated with Mn, Fe, rare-earth elements, Sr, and Na. The e xcessive Zr atoms are located in octahedra participating in the formation o f a new type of a TiZr3 cluster.
