AgH2(CN)4 crystallizes in the orthorhombic Fddd space group. Ag(1) is bonded in a tetrahedral geometry to two equivalent N(1) and two equivalent N(2) atoms. Both Ag(1)-N(1) bond lengths are 2.41 Å. Both Ag(1)-N(2) bond lengths are 2.28 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted single-bond geometry to one C(2) and one H(1) atom. The C(1)-C(2) bond length is 1.40 Å. The C(1)-H(1) bond length is 1.09 Å. In the second C site, C(2) is bonded in a trigonal planar geometry to one C(3) and two equivalent C(1) atoms. The C(2)-C(3) bond length is 1.46 Å. In the third C site, C(3) is bonded in a distorted trigonal planar geometry to one C(2) and two equivalent N(1) atoms. Both C(3)-N(1) bond lengths are 1.35 Å. There are two inequivalent N sites. In the first N site, N(2) is bonded in a trigonal planar geometry to one Ag(1), one N(1), and one N(2) atom. The N(2)-N(1) bond length is 1.34 Å. The N(2)-N(2) bond length is 1.32 Å. In the second N site, N(1) is bonded in a 3-coordinate geometry to one Ag(1), one C(3), and one N(2) atom. H(1) is bonded in a single-bond geometry to one C(1) atom. Linkers: 2 c1cc(C2=NN=N[N]2)ccc1C1=NN=N[N]1. Metal clusters: 4 [Ag].
