Description
Summary:Using selected aeria difraction and X-ray powder data, a structural model was constructed for the rare mineral vyalsovite FeCaAlS(OH).sub.5. Parameters of the elementary monoclinic cell а 5.205, b 21.402, c 14.400 Å, [beta] 95°, sp. gr. C.sub.m. The crystal structure of vyalsovite is the first example of a hybrid structure composed of commensurate iron sulfide and hydroxide modules.
