In the Lu-V-Ge system a formation of the substitutional solid solution Lu<sub>5</sub>Ge<sub>3-</sub><em><sub>x</sub></em>V<em><sub>x</sub></em>&nbsp;based on the Lu<sub>5</sub>Ge<sub>3</sub>binary compound (Mn<sub>5</sub>Si<sub>3</sub>&nbsp;structure type) was found up to 6 at. % V. Insertion of the V atoms in the structure of the LuGe<sub>2</sub>&nbsp;binary germanide (ZrSi<sub>2</sub>structure type, up to 5 aт. % V) results in the formation of the LuV<sub>0,15</sub>Ge<sub>2</sub>&nbsp;ternary phase (CeNiSi<sub>2</sub>&nbsp;structure type, space group&nbsp;<em>Cmcm</em>,&nbsp;<em>a</em>=0.40210(4),<em>b</em>=1.5661(1),&nbsp;<em>c</em>=0.38876(3) nm), which corresponds to the limit composition of the interstitial solid solution LuV<em><sub>x</sub></em>Ge<sub>2</sub>. The interaction between the elements in the Lu-V-Sn system results in the formation of one ternary compound LuV<sub>6</sub>Sn<sub>6</sub>&nbsp;(SmMn<sub>6</sub>Sn<sub>6</sub>-type,<em>&nbsp;</em>space group&nbsp;<em>P</em>6/<em>mmm</em>,&nbsp;<em>a</em>=0.5503(2),&nbsp;<em>c</em>=0.9171(4) nm) at investigated temperature.</p></div> ER -
