Materials Data on CoAsPd by Materials Project
CoPdAs is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Co1+ is bonded to five equivalent As3- atoms to form a mixture of distorted corner and edge-sharing CoAs5 square pyramids. There are one shorter (2.22 Å) and four longer (2.69 Å) Co–As bond lengths. Pd2+ is bonded in a 8-coordinate geometry to four equivalent Pd2+ and four equivalent As3- atoms. All Pd–Pd bond lengths are 2.64 Å. All Pd–As bond lengths are 2.58 Å. As3- is bonded in a 1-coordinate geometry to five equivalent Co1+ and four equivalent Pd2+ atoms.
