AgIn3C21N3H9O13 crystallizes in the hexagonal P-62c space group. Ag(1) is bonded in a trigonal planar geometry to three equivalent N(1) atoms. All Ag(1)-N(1) bond lengths are 2.26 Å. In(1) is bonded to one O(3), two equivalent O(1), and two equivalent O(2) atoms to form distorted corner-sharing InO5 square pyramids. The In(1)-O(3) bond length is 2.04 Å. Both In(1)-O(1) bond lengths are 2.17 Å. Both In(1)-O(2) bond lengths are 2.17 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one C(2), one C(3), and one C(4) atom. The C(1)-C(2) bond length is 1.50 Å. The C(1)-C(3) bond length is 1.38 Å. The C(1)-C(4) bond length is 1.41 Å. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one C(1), one O(1), and one O(2) atom. The C(2)-O(1) bond length is 1.27 Å. The C(2)-O(2) bond length is 1.24 Å. In the third C site, C(3) is bonded in a distorted bent 120 degrees geometry to one C(1), one N(1), and one H(1) atom. The C(3)-N(1) bond length is 1.33 Å.
