Materials Data on Pr2(TlIn)3 by Materials Project
Pr2(TlIn)3 is beta Cu3Ti-derived structured and crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. Pr is bonded to six Tl and six In atoms to form PrTl6In6 cuboctahedra that share corners with twelve equivalent PrTl6In6 cuboctahedra, edges with twelve TlPr4Tl4In4 cuboctahedra, edges with twelve InPr4Tl6In2 cuboctahedra, faces with six equivalent PrTl6In6 cuboctahedra, faces with six TlPr4Tl4In4 cuboctahedra, and faces with six InPr4Tl6In2 cuboctahedra. There are a spread of Pr–Tl bond distances ranging from 3.38–3.40 Å. There are two shorter (3.39 Å) and four longer (3.42 Å) Pr–In bond lengths. There are three inequivalent Tl sites. In the first Tl site, Tl is bonded to four equivalent Pr, four equivalent Tl, and four equivalent In atoms to form distorted TlPr4Tl4In4 cuboctahedra that share corners with four equivalent TlPr4Tl4In4 cuboctahedra, corners with eight equivalent InPr4Tl4In4 cuboctahedra, edges with eight equivalent PrTl6In6 cuboctahedra, edges with eight equivalent TlPr4In8 cuboctahedra, edges with eight equivalent InPr4Tl6In2 cuboctahedra, faces with four equivalent PrTl6In6 cuboctahedra, faces with six InPr4Tl6In2 cuboctahedra, and faces with eight TlPr4Tl4In4 cuboctahedra. All Tl–Tl bond lengths are 3.42 Å. All Tl–In bond lengths are 3.40 Å. In the second Tl site, Tl is bonded to four equivalent Pr and eight In atoms to form TlPr4In8 cuboctahedra that share corners with twelve TlPr4In8 cuboctahedra, edges with eight equivalent PrTl6In6 cuboctahedra, edges with eight equivalent TlPr4Tl4In4 cuboctahedra, edges with eight equivalent InPr4Tl6In2 cuboctahedra, faces with four equivalent PrTl6In6 cuboctahedra, faces with six TlPr4In8 cuboctahedra, and faces with eight InPr4Tl6In2 cuboctahedra. There are four shorter (3.38 Å) and four longer (3.42 Å) Tl–In bond lengths. In the third Tl site, Tl is bonded to four equivalent Pr, four equivalent Tl, and four equivalent In atoms to form distorted TlPr4Tl4In4 cuboctahedra that share corners with twelve TlPr4In8 cuboctahedra, edges with eight equivalent PrTl6In6 cuboctahedra, edges with sixteen InPr4Tl6In2 cuboctahedra, faces with four equivalent PrTl6In6 cuboctahedra, faces with four equivalent InPr4Tl6In2 cuboctahedra, and faces with ten TlPr4Tl4In4 cuboctahedra. All Tl–In bond lengths are 3.41 Å. There are two inequivalent In sites. In the first In site, In is bonded to four equivalent Pr, six Tl, and two equivalent In atoms to form distorted InPr4Tl6In2 cuboctahedra that share corners with twelve equivalent InPr4Tl6In2 cuboctahedra, edges with four equivalent InPr4Tl4In4 cuboctahedra, edges with eight equivalent PrTl6In6 cuboctahedra, edges with twelve TlPr4Tl4In4 cuboctahedra, faces with four equivalent PrTl6In6 cuboctahedra, faces with six TlPr4Tl4In4 cuboctahedra, and faces with eight InPr4Tl6In2 cuboctahedra. Both In–In bond lengths are 3.36 Å. In the second In site, In is bonded to four equivalent Pr, four equivalent Tl, and four equivalent In atoms to form distorted InPr4Tl4In4 cuboctahedra that share corners with four equivalent InPr4Tl4In4 cuboctahedra, corners with eight equivalent TlPr4Tl4In4 cuboctahedra, edges with eight equivalent PrTl6In6 cuboctahedra, edges with eight equivalent TlPr4Tl4In4 cuboctahedra, edges with eight equivalent InPr4Tl6In2 cuboctahedra, faces with four equivalent PrTl6In6 cuboctahedra, faces with six TlPr4Tl4In4 cuboctahedra, and faces with eight InPr4Tl6In2 cuboctahedra.
