Ag3C2H2(N3O)3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent O(2) atoms. Both Ag(1)-N(1) bond lengths are 2.14 Å. Both Ag(1)-O(2) bond lengths are 2.69 Å. In the second Ag site, Ag(2) is bonded in a 5-coordinate geometry to one N(2), one N(3), one N(4), one O(1), and one O(2) atom. The Ag(2)-N(2) bond length is 2.39 Å. The Ag(2)-N(3) bond length is 2.25 Å. The Ag(2)-N(4) bond length is 2.21 Å. The Ag(2)-O(1) bond length is 2.66 Å. The Ag(2)-O(2) bond length is 2.78 Å. C(1) is bonded in a trigonal planar geometry to one N(1), one N(4), and one H(1) atom. The C(1)-N(1) bond length is 1.34 Å. The C(1)-N(4) bond length is 1.34 Å. The C(1)-H(1) bond length is 1.09 Å. There are five inequivalent N sites. In the first N site, N(2) is bonded in a trigonal planar geometry to one Ag(2), one N(1), and one N(3) atom. The N(2)-N(1) bond length is 1.35 Å. The N(2)-N(3) bond length is 1.32 Å. In the second N site, N(3) is bonded in a trigonal planar geometry to one Ag(2), one N(2), and one N(4) atom. The N(3)-N(4) bond length is 1.35 Å. In the third N site, N(4) is bonded in a distorted trigonal planar geometry to one Ag(2), one C(1), and one N(3) atom. In the fourth N site, N(5) is bonded in a trigonal planar geometry to one O(1) and two equivalent O(2) atoms. The N(5)-O(1) bond length is 1.27 Å. Both N(5)-O(2) bond lengths are 1.27 Å. In the fifth N site, N(1) is bonded in a 3-coordinate geometry to one Ag(1), one C(1), and one N(2) atom. H(1) is bonded in a single-bond geometry to one C(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Ag(2) and one N(5) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Ag(1), one Ag(2), and one N(5) atom. Linkers: 4 C1=NN=N[N]1. Metal clusters: 6 [Ag].
