The material structure described by (NH4)2MoO4 is Indium-like structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of four (NH4)2MoO4 clusters. Mo(1) is bonded in a 5-coordinate geometry to one N(1), one O(1), one O(3), and two equivalent O(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal non-coplanar geometry to one Mo(1), one H(1), and two equivalent H(3) atoms. In the second N site, N(2) is bonded in a tetrahedral geometry to one H(4), one H(6), and two equivalent H(5) atoms. There are six inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(3) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(1) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one N(2) and one O(1) atom. In the fifth H site, H(5) is bonded in a single-bond geometry to one N(2) atom. In the sixth H site, H(6) is bonded in a single-bond geometry to one N(2) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Mo(1) and one H(4) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Mo(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Mo(1) and one H(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
