AgH8(C3N)4 is Indium-like structured and crystallizes in the tetragonal P4bm space group. The structure is zero-dimensional and consists of two AgH8(C3N)4 clusters. Ag(1) is bonded in a distorted tetrahedral geometry to two equivalent N(1) and two equivalent N(2) atoms. Both Ag(1)-N(1) bond lengths are 2.28 Å. Both Ag(1)-N(2) bond lengths are 2.35 Å. There are four inequivalent C sites. In the first C site, C(3) is bonded in a trigonal planar geometry to one C(4) and two equivalent C(2) atoms. The C(3)-C(4) bond length is 1.42 Å. Both C(3)-C(2) bond lengths are 1.38 Å. In the second C site, C(4) is bonded in a distorted linear geometry to one C(3) and one N(2) atom. The C(4)-N(2) bond length is 1.13 Å. In the third C site, C(1) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(1) atom. The C(1)-N(1) bond length is 1.33 Å. The C(1)-H(1) bond length is 0.93 Å. In the fourth C site, C(2) is bonded in a distorted single-bond geometry to one C(3) and one H(2) atom. The C(2)-H(2) bond length is 0.93 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Ag(1) and two equivalent C(1) atoms. In the second N site, N(2) is bonded in a linear geometry to one Ag(1) and one C(4) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom.
