Co Si Si Pd
CoPdSi2 crystallizes in the monoclinic Cm space group. Co(1) is bonded in a single-bond geometry to one Si(1) and four equivalent Si(2) atoms. The Co(1)-Si(1) bond length is 1.11 Å. There are a spread of Co(1)-Si(2) bond distances ranging from 2.24-3.00 Å. Pd(1) is bonded in a 1-coordinate geometry to two equivalent Si(2) and four equivalent Si(1) atoms. There is one shorter (2.49 Å) and one longer (2.57 Å) Pd(1)-Si(2) bond length. There are a spread of Pd(1)-Si(1) bond distances ranging from 1.82-2.70 Å. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 5-coordinate geometry to one Co(1) and four equivalent Pd(1) atoms. In the second Si site, Si(2) is bonded in a 6-coordinate geometry to four equivalent Co(1) and two equivalent Pd(1) atoms.
