The compound described by Yb3Tc is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 4-coordinate geometry to four equivalent Yb(2) and four equivalent Tc(1) atoms. In the second Yb site, Yb(2) is bonded to eight equivalent Yb(1) and four equivalent Tc(1) atoms to form YbYb8Tc4 cuboctahedra that share corners with four equivalent Yb(2)Yb8Tc4 cuboctahedra, corners with eight equivalent Tc(1)Yb12 cuboctahedra, edges with eight equivalent Yb(2)Yb8Tc4 cuboctahedra, faces with four equivalent Yb(2)Yb8Tc4 cuboctahedra, and faces with six equivalent Tc(1)Yb12 cuboctahedra. Tc(1) is bonded to four equivalent Yb(2) and eight equivalent Yb(1) atoms to form TcYb12 cuboctahedra that share corners with four equivalent Tc(1)Yb12 cuboctahedra, corners with eight equivalent Yb(2)Yb8Tc4 cuboctahedra, edges with eight equivalent Tc(1)Yb12 cuboctahedra, faces with four equivalent Tc(1)Yb12 cuboctahedra, and faces with six equivalent Yb(2)Yb8Tc4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
