Ba3Mo2(NO3)2 crystallizes in the trigonal R-3m space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 10-coordinate geometry to one N(1) and nine equivalent O(1) atoms. In the second Ba site, Ba(2) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Mo(1) is bonded in a tetrahedral geometry to one N(1) and three equivalent O(1) atoms. N(1) is bonded in a distorted linear geometry to one Ba(1) and one Mo(1) atom. O(1) is bonded in a 5-coordinate geometry to one Ba(2), three equivalent Ba(1), and one Mo(1) atom.
