description: TaC8N4H24Cl crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four TaC8N4H24Cl clusters. Ta5+ is bonded to four N3- and one Cl1- atom to form TaN4Cl trigonal bipyramids that share corners with eight CH3N tetrahedra. There are a spread of Ta–N bond distances ranging from 1.99–2.04 Å. The Ta–Cl bond length is 2.50 Å. There are eight inequivalent C2- sites. In the first C2- site, C2- is bonded to one N3- and three H1+ atoms to form CH3N tetrahedra that share a cornercorner with one CH3N tetrahedra and a cornercorner with one TaN4Cl trigonal bipyramid. The C–N bond length is 1.46 Å. There is one shorter (1.10 Å) and two longer (1.11 Å) C–H bond length. In the second C2- site, C2- is bonded to one N3- and three H1+ atoms to form CH3N tetrahedra that share a cornercorner with one CH3N tetrahedra and a cornercorner with one TaN4Cl trigonal bipyramid. The C–N bond length is 1.45 Å. There is two shorter (1.10 Å) and one longer (1.11 Å) C–H bond length. In the third C2- site, C2- is bonded to one N3- and three H1+ atoms to form CH3N tetrahedra that share a cornercorner with one CH3N tetrahedra and a cornercorner with one TaN4Cl trigonal bipyramid. The C–N bond length is 1.45 Å. There is two shorter (1.10 Å) and one longer (1.11 Å) C–H bond length. In the fourth C2- site, C2- is bonded to one N3- and three H1+ atoms to form CH3N tetrahedra that share a cornercorner with one CH3N tetrahedra and a cornercorner with one TaN4Cl trigonal bipyramid. The C–N bond length is 1.46 Å. There is one shorter (1.09 Å) and two longer (1.11 Å) C–H bond length. In the fifth C2- site, C2- is bonded to one N3- and three H1+ atoms to form CH3N tetrahedra that share a cornercorner with one CH3N tetrahedra and a cornercorner with one TaN4Cl trigonal bipyramid.

In the sixth C2- site, C2- is bonded to one N3- and three H1+ atoms to form CH3N tetrahedra that share a cornercorner with one CH3N tetrahedra and a cornercorner with one TaN4Cl trigonal bipyramid. The C–N bond length is 1.46 Å. There is one shorter (1.09 Å) and two longer (1.11 Å) C–H bond length. In the seventh C2- site, C2- is bonded to one N3- and three H1+ atoms to form CH3N tetrahedra that share a cornercorner with one CH3N tetrahedra and a cornercorner with one TaN4Cl trigonal bipyramid.

In the eighth C2- site, C2- is bonded to one N3- and three H1+ atoms to form CH3N tetrahedra that share a cornercorner with one CH3N tetrahedra and a cornercorner with one TaN4Cl trigonal bipyramid. The C–N bond length is 1.46 Å. There is one shorter (1.10 Å) and two longer (1.11 Å) C–H bond length. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded in a trigonal planar geometry to one Ta5+ and two C2- atoms. In the second N3- site, N3- is bonded in a trigonal planar geometry to one Ta5+ and two C2- atoms. In the third N3- site, N3- is bonded in a trigonal planar geometry to one Ta5+ and two C2- atoms. In the fourth N3- site, N3- is bonded in a trigonal planar geometry to one Ta5+ and two C2- atoms.
