The structure described by V20As11 crystallizes in the orthorhombic C222 space group. There are five inequivalent V sites. In the first V site, V(1) is bonded in a 4-coordinate geometry to one As(1), one As(2), and two equivalent As(3) atoms. In the second V site, V(2) is bonded in a 6-coordinate geometry to one As(2), one As(4), one As(6), and three equivalent As(3) atoms. In the third V site, V(3) is bonded in a 5-coordinate geometry to one As(1), one As(5), and three equivalent As(3) atoms. In the fourth V site, V(4) is bonded in a 5-coordinate geometry to one As(3), one As(5), and three equivalent As(1) atoms. In the fifth V site, V(5) is bonded in a 6-coordinate geometry to one As(3), one As(4), one As(6), and three equivalent As(2) atoms. There are six inequivalent As sites. In the first As site, As(1) is bonded in a 10-coordinate geometry to two equivalent V(1), two equivalent V(3), and six equivalent V(4) atoms. In the second As site, As(2) is bonded in a 10-coordinate geometry to two equivalent V(1), two equivalent V(2), and six equivalent V(5) atoms. In the third As site, As(3) is bonded in a 10-coordinate geometry to one V(4), one V(5), two equivalent V(1), three equivalent V(2), and three equivalent V(3) atoms. In the fourth As site, As(4) is bonded in a 10-coordinate geometry to four equivalent V(2), four equivalent V(5), and two equivalent As(6) atoms. In the fifth As site, As(5) is bonded in a 8-coordinate geometry to four equivalent V(3) and four equivalent V(4) atoms. In the sixth As site, As(6) is bonded in a 10-coordinate geometry to four equivalent V(2), four equivalent V(5), and two equivalent As(4) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
