description: UC12P2H36Br2(N3O2)2 crystallizes in the tetragonal P4_12_12 space group. The structure is zero-dimensional and consists of four UC12P2H36Br2(N3O2)2 clusters. U6+ is bonded to four O2- and two Br1- atoms to form distorted UBr2O4 octahedra that share corners with two equivalent PN3O tetrahedra. There are two shorter (1.81 Å) and two longer (2.33 Å) U–O bond lengths. There are one shorter (2.84 Å) and one longer (2.86 Å) U–Br bond lengths. There are six 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 PN3O tetrahedra. The C–N bond length is 1.46 Å. All C–H bond lengths are 1.10 Å. 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 PN3O tetrahedra. The C–N bond length is 1.46 Å. There is one shorter (1.09 Å) and two longer (1.10 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 PN3O tetrahedra. The C–N bond length is 1.46 Å. There is one shorter (1.09 Å) and two longer (1.10 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 PN3O tetrahedra. The C–N bond length is 1.46 Å. All C–H bond lengths are 1.10 Å. 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 PN3O tetrahedra. The C–N bond length is 1.46 Å. There is one shorter (1.09 Å) and two longer (1.10 Å) C–H bond length. 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 PN3O tetrahedra. The C–N bond length is 1.46 Å. There is one shorter (1.09 Å) and two longer (1.10 Å) C–H bond length. P5+ is bonded to three N3- and one O2- atom to form PN3O tetrahedra that share a cornercorner with one UBr2O4 octahedra and corners with six CH3N tetrahedra. The corner-sharing octahedral tilt angles are 3°. There is one shorter (1.64 Å) and two longer (1.65 Å) P–N bond length. The P–O bond length is 1.53 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a trigonal planar geometry to two C2- and one P5+ atom. In the second N3- site, N3- is bonded in a trigonal planar geometry to two C2- and one P5+ atom. In the third N3- site, N3- is bonded in a trigonal planar geometry to two C2- and one P5+ atom. There are eighteen inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one C2- atom.
