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.
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 is one shorter (2.58 Å) and two longer (2.59 Å) W(1)-As(2) bond lengths. There are a spread of W(1)-As(1) bond distances ranging from 2.61-2.75 Å. 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. There is one shorter (2.43 Å) and two longer (2.76 Å) As(2)-As(2) bond lengths.
