Sr2(OH)3NO3 crystallizes in the hexagonal P-62m space group. Sr(1) is bonded in a 9-coordinate geometry to three equivalent O(1) and six equivalent O(2) atoms. N(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. H(1) is bonded in a single-bond geometry to one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to two equivalent Sr(1) and one N(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to four equivalent Sr(1) and one H(1) atom.
