Zr9Co7In14 crystallizes in the cubic system, space group Fm (3) over b
ar m, a = 13.300(2) Angstrom, Z = 2, R = 0.0412 for 567 unique reflect
ion (KM-4 diffractometer, Mo K alpha radiation). The crystal structure
, related to the Cr23C6-type structure, can be described as a stacking
of columns of cubes, tetragonal antiprisms, and cubo-octahedrons exte
nding along the coordinate axes. One of the In atoms is coordinated by
a Frank-Kasper polyhedron.
