The structure described by CaWAs2O7 crystallizes in the monoclinic P2_1/c space group. Ca(1) is bonded in a 6-coordinate geometry to one O(1), one O(5), one O(6), one O(7), and two equivalent O(3) atoms. W(1) is bonded in a trigonal bipyramidal geometry to one O(1), one O(2), one O(5), one O(6), and one O(7) atom. There are two inequivalent As sites. In the first As site, As(1) is bonded in a distorted trigonal non-coplanar geometry to one O(2), one O(3), and one O(4) atom. In the second As site, As(2) is bonded in a 3-coordinate geometry to one O(4), one O(5), and one O(7) atom. There are seven inequivalent O sites. In the first O site, O(5) is bonded in a distorted trigonal planar geometry to one Ca(1), one W(1), and one As(2) atom. In the second O site, O(6) is bonded in a distorted L-shaped geometry to one Ca(1) and one W(1) atom. In the third O site, O(7) is bonded in a distorted trigonal planar geometry to one Ca(1), one W(1), and one As(2) atom. In the fourth O site, O(1) is bonded in a water-like geometry to one Ca(1) and one W(1) atom. In the fifth O site, O(2) is bonded in a bent 150 degrees geometry to one W(1) and one As(1) atom. In the sixth O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ca(1) and one As(1) atom. In the seventh O site, O(4) is bonded in a bent 120 degrees geometry to one As(1) and one As(2) atom. is represented by the CIF card [CIF]
