Materials Data on Pu3In by Materials Project
Pu3In is Uranium Silicide structured and crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are three inequivalent Pu sites. In the first Pu site, Pu is bonded to eight Pu and four equivalent In atoms to form distorted PuPu8In4 cuboctahedra that share corners with twelve equivalent PuPu8In4 cuboctahedra, edges with eight equivalent InPu12 cuboctahedra, edges with sixteen PuPu8In4 cuboctahedra, faces with four equivalent InPu12 cuboctahedra, and faces with fourteen PuPu8In4 cuboctahedra. There are six shorter (3.07 Å) and two longer (3.08 Å) Pu–Pu bond lengths. All Pu–In bond lengths are 3.07 Å. In the second Pu site, Pu is bonded to eight Pu and four equivalent In atoms to form distorted PuPu8In4 cuboctahedra that share corners with twelve equivalent PuPu8In4 cuboctahedra, edges with eight equivalent InPu12 cuboctahedra, edges with sixteen PuPu8In4 cuboctahedra, faces with four equivalent InPu12 cuboctahedra, and faces with fourteen PuPu8In4 cuboctahedra. There are two shorter (3.07 Å) and two longer (3.08 Å) Pu–Pu bond lengths. All Pu–In bond lengths are 3.07 Å. In the third Pu site, Pu is bonded to eight Pu and four equivalent In atoms to form distorted PuPu8In4 cuboctahedra that share corners with twelve equivalent PuPu8In4 cuboctahedra, edges with eight equivalent InPu12 cuboctahedra, edges with sixteen PuPu8In4 cuboctahedra, faces with four equivalent InPu12 cuboctahedra, and faces with fourteen PuPu8In4 cuboctahedra. All Pu–In bond lengths are 3.08 Å. In is bonded to twelve Pu atoms to form InPu12 cuboctahedra that share corners with twelve equivalent InPu12 cuboctahedra, edges with twenty-four PuPu8In4 cuboctahedra, faces with six equivalent InPu12 cuboctahedra, and faces with twelve PuPu8In4 cuboctahedra.
