The compound described by (CrO8)2(N2)3 is beta Cu3Ti structured and crystallizes in the orthorhombic Pca2_1 space group. The structure is zero-dimensional and consists of twelve ammonia atoms and four CrO8 clusters. In each CrO8 cluster, Cr(1) is bonded in a hexagonal bipyramidal geometry to one O(1), one O(2), one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Cr(1) and one O(2) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Cr(1) and one O(1) atom. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Cr(1) and one O(4) atom. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to one Cr(1) and one O(3) atom. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to one Cr(1) and one O(7) atom. In the sixth O site, O(6) is bonded in a 2-coordinate geometry to one Cr(1) and one O(8) atom. In the seventh O site, O(7) is bonded in a 2-coordinate geometry to one Cr(1) and one O(5) atom. In the eighth O site, O(8) is bonded in a 2-coordinate geometry to one Cr(1) and one O(6) atom. is represented by the CIF card [CIF]
