The compound described by WAs2 is Magnesium tetraboride-like structured and crystallizes in the monoclinic C2/m space group. W(1) is bonded in a 8-coordinate geometry to three equivalent As(2) and five equivalent As(1) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 5-coordinate geometry to five equivalent W(1) atoms. In the second As site, As(2) is bonded in a 6-coordinate geometry to three equivalent W(1) and three equivalent As(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
