The crystal structures of Tb(Al 0.15 Si 0.85 ), (Tb 0.70 Zr 0.30 )(Al 0.17 Si 0.83 ) and Zr(Al 0.22 Si 0.78 ) have been refined from single‐crystal X‐ray diffraction data. The three compounds crystallize with CrB‐type structures (Pearson symbol oS 8, space group Cmcm ): Tb(Al 0.15 Si 0.85 ): a = 4.2715(5), b = 10.5595(15), c = 3.8393(5) Å; (Tb 0.70 Zr 0.30 )(Al 0.17 Si 0.83 ): a = 4.163(2), b = 10.423(5), c = 3.8543(18) Å; Zr(Al 0.22 Si 0.78 ): a = 3.7824(6), b = 10.0164(16), c = 3.7795(5) Å. The existence of a significant CrB‐type solid solution in the quaternary system Tb‐Zr‐Al‐Si, based on the ternary compound Tb(Al 0.15 Si 0.85 ) and extending toward the solid solution based on the binary compound ZrSi in the Zr‐Al‐Si system, cannot be excluded.
