Variations of the FeGa3 structure type in the systems CoIn3-xZnx and CoGa3-xZnx
We present an investigation of the quasibinary systems CoIn3-xZnx and CoGa3-xZnx which were structurally characterized by X-ray diffraction experiments and, in the case of CoGa3-xZnx, additionally by neutron powder diffraction experiments. The limiting compositions were found to be x=0.81(2) and x=0.73(2) for COIn3-xZnx and CoGa3-xZnx, respectively. The isotypic binary compounds CoIn3 and CoGa3 cr
