The Materials Project

UCoAs2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. U4+ is bonded in a 8-coordinate geometry to eight As3- atoms. There are four shorter (2.94 Å) and four longer (3.01 Å) U–As bond lengths. Co2+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing CoAs4 tetrahedra. All Co–As bond lengths are 2.43 Å. There are two inequivalent As3- sites. In the first As3- site, As3- is bonded in a 8-coordinate geometry to four equivalent U4+ and four equivalent Co2+ atoms. In the second As3- site, As3- is bonded in a 8-coordinate geometry to four equivalent U4+ and four equivalent As3- atoms. All As–As bond lengths are 2.82 Å.
