SrH6(C3N2)2 crystallizes in the monoclinic C2/c space group. Sr(1) is bonded in a 6-coordinate geometry to two equivalent N(2) and four equivalent N(1) atoms. Both Sr(1)-N(2) bond lengths are 2.64 Å. There are two shorter (2.64 Å) and two longer (2.79 Å) Sr(1)-N(1) bond lengths. There are three inequivalent C sites. In the first C site, C(2) is bonded in a distorted bent 120 degrees geometry to one N(2) and one H(2) atom. The C(2)-N(2) bond length is 1.38 Å. The C(2)-H(2) bond length is 1.08 Å. In the second C site, C(3) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(3) atom. The C(3)-N(1) bond length is 1.39 Å. The C(3)-H(3) bond length is 1.09 Å. In the third C site, C(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one H(1) atom. The C(1)-N(1) bond length is 1.36 Å. The C(1)-N(2) bond length is 1.35 Å. The C(1)-H(1) bond length is 1.09 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted water-like geometry to two equivalent Sr(1), one C(1), and one C(3) atom. In the second N site, N(2) is bonded in a distorted water-like geometry to one Sr(1), one C(1), and one C(2) atom. There are three 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. In the third H site, H(3) is bonded in a single-bond geometry to one C(3) atom. Linkers: 4 [CH]1C=NC=N1. Metal clusters: 2 [Sr].
