Co Si Rh Rh Rh Rh
Rh4CoSi crystallizes in the trigonal R3m space group. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 9-coordinate geometry to three equivalent Rh(1), three equivalent Co(1), and three equivalent Si(1) atoms. All Rh(2)-Rh(1) bond lengths are 1.97 Å. All Rh(2)-Co(1) bond lengths are 2.90 Å. All Rh(2)-Si(1) bond lengths are 2.90 Å. In the second Rh site, Rh(1) is bonded in a 2-coordinate geometry to one Rh(2), two equivalent Rh(1), two equivalent Co(1), and one Si(1) atom. Both Rh(1)-Rh(1) bond lengths are 1.14 Å. There is one shorter (2.38 Å) and one longer (2.89 Å) Rh(1)-Co(1) bond length. The Rh(1)-Si(1) bond length is 3.17 Å. Co(1) is bonded to three equivalent Rh(2), six equivalent Rh(1), and three equivalent Si(1) atoms to form a mixture of distorted edge and corner-sharing CoSi3Rh9 cuboctahedra. All Co(1)-Si(1) bond lengths are 2.90 Å. Si(1) is bonded in a 9-coordinate geometry to three equivalent Rh(1), three equivalent Rh(2), and three equivalent Co(1) atoms.
