(In2Se3)6N2Se crystallizes in the trigonal R-3 space group. The structure consists of three 7782-49-2 atoms and six ammonia atoms inside a In2Se3 framework. In the In2Se3 framework, there are two inequivalent In sites. In the first In site, In(1) is bonded to one Se(1), one Se(3), and two equivalent Se(4) atoms to form corner-sharing InSe4 tetrahedra. In the second In site, In(2) is bonded to two equivalent Se(1) and two equivalent Se(3) atoms to form a mixture of corner and edge-sharing InSe4 trigonal pyramids. There are three inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted T-shaped geometry to one In(1) and two equivalent In(2) atoms. In the second Se site, Se(3) is bonded in a trigonal non-coplanar geometry to one In(1) and two equivalent In(2) atoms. In the third Se site, Se(4) is bonded in a water-like geometry to two equivalent In(1) atoms.

The In(1)-Se(1) bond length is 2.68 Å. The In(1)-Se(3) bond length is 2.70 Å. There is one shorter (2.57 Å) and one longer (2.58 Å) In(1)-Se(4) bond length. In the second In site, In(2) is bonded to two equivalent Se(1) and two equivalent Se(3) atoms to form a mixture of corner and edge-sharing InSe4 trigonal pyramids. There is one shorter (2.60 Å) and one longer (2.86 Å) In(2)-Se(1) bond length. There is one shorter (2.62 Å) and one longer (2.64 Å) In(2)-Se(3) bond length. There are three inequivalent Se sites.
