AgH12(C3N2)2 crystallizes in the cubic P2_13 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 2.36 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded to one N(1), one N(2), one H(1), and one H(2) atom to form corner-sharing CH2N2 tetrahedra. The C(1)-N(1) bond length is 1.49 Å. The C(1)-N(2) bond length is 1.46 Å. The C(1)-H(1) bond length is 0.97 Å. The C(1)-H(2) bond length is 0.95 Å. In the second C site, C(2) is bonded to two equivalent N(1), one H(3), and one H(4) atom to form corner-sharing CH2N2 tetrahedra. There is one shorter (1.48 Å) and one longer (1.49 Å) C(2)-N(1) bond length. The C(2)-H(3) bond length is 1.03 Å. The C(2)-H(4) bond length is 1.03 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Ag(1), one C(1), and two equivalent C(2) atoms to form distorted corner-sharing NAgC3 tetrahedra. In the second N site, N(2) is bonded in a trigonal non-coplanar geometry to three equivalent C(1) atoms. There are four 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(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one C(2) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one C(2) atom. Linkers: 4 C1N2CN3CN1CN(C2)C3.
