There are six inequivalent N3- sites. In the first N3- site, N3- is bonded in a trigonal planar geometry to one Co3+ and two O2- atoms. There is one shorter (1.25 Å) and one longer (1.26 Å) N–O bond length. In the second N3- site, N3- is bonded in a trigonal planar geometry to one Co3+ and two O2- atoms. Both N–O bond lengths are 1.25 Å. In the third N3- site, N3- is bonded to one Co3+, one C4+, and two H1+ atoms to form distorted corner-sharing NCoH2C tetrahedra. Both N–H bond lengths are 1.03 Å. In the fourth N3- site, N3- is bonded to one Co3+, one C4+, and two H1+ atoms to form distorted corner-sharing NCoH2C tetrahedra. Both N–H bond lengths are 1.03 Å. In the fifth N3- site, N3- is bonded to one Co3+, one C4+, and two H1+ atoms to form distorted corner-sharing NCoH2C tetrahedra. Both N–H bond lengths are 1.03 Å. In the sixth N3- site, N3- is bonded to one Co3+, one C4+, and two H1+ atoms to form distorted corner-sharing NCoH2C tetrahedra. Both N–H bond lengths are 1.03 Å. There are sixteen inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C4+ atom.
