Materials Data on CuSb2(XeF5)4 by Materials Project
CuSb(Xe2F7)2SbF6 crystallizes in the tetragonal I-4 space group. The structure is one-dimensional and consists of two SbF6 clusters and two CuSb(Xe2F7)2 ribbons oriented in the (0, 0, 1) direction. In each SbF6 cluster, Sb is bonded in an octahedral geometry to six F atoms. There is four shorter (1.92 Å) and two longer (1.93 Å) Sb–F bond length. There are two inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Sb atom. In the second F site, F is bonded in a single-bond geometry to one Sb atom. In each CuSb(Xe2F7)2 ribbon, Xe is bonded in a linear geometry to two F atoms. There are one shorter (2.02 Å) and one longer (2.18 Å) Xe–F bond lengths. Cu is bonded to six F atoms to form CuF6 octahedra that share corners with two equivalent SbF6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (1.93 Å) and two longer (2.30 Å) Cu–F bond lengths. Sb is bonded to six F atoms to form SbF6 octahedra that share corners with two equivalent CuF6 octahedra. The corner-sharing octahedral tilt angles are 0°. There is four shorter (1.91 Å) and two longer (1.95 Å) Sb–F bond length. There are four inequivalent F sites. In the first F site, F is bonded in a bent 120 degrees geometry to one Xe and one Cu atom. In the second F site, F is bonded in a single-bond geometry to one Xe atom. In the third F site, F is bonded in a single-bond geometry to one Sb atom. In the fourth F site, F is bonded in a linear geometry to one Cu and one Sb atom.
