Ak. Larsson et S. Lidin, THE COSN TYPE-STRUCTURE OF (FE0.6,CR0.2,NI0.2)SN, Acta crystallographica. Section C, Crystal structure communications, 50, 1994, pp. 13-15
The structure of (Fe0.6,Cr0.2,Ni0.2)Sn is of the CoSn structure type w
ith Fe, Cr and Ni disordered in the Co position. The structure contain
s a void surrounded by a 20-vertex polyhedron. The coordination polyhe
dra for Sn are hexagons and edge-capped trigonal prisms, and for Fe, t
en-vertex polyhedra.
