The material described by TaAs2 crystallizes in the monoclinic C2/m space group. Ta(1) is bonded in a 8-coordinate geometry to three equivalent As(1) and five equivalent As(2) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 6-coordinate geometry to three equivalent Ta(1) and three equivalent As(1) atoms. In the second As site, As(2) is bonded in a 5-coordinate geometry to five equivalent Ta(1) atoms. is represented by the CIF card [CIF]
