Abstract

Li(H2O)4Al(CO)4(CF3)12 crystallizes in the tetragonal I-4 space group. The structure is zero-dimensional and consists of twenty-four fluoroform molecules, two Al(CO)4 clusters, and two Li(H2O)4 clusters. In each Al(CO)4 cluster, Al3+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Al–O bond lengths are 1.75 Å. C+2.50+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.35 Å. O2- is bonded in a bent 150 degrees geometry to one Al3+ and one C+2.50+ atom. In each Li(H2O)4 cluster, Li1+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Li–O bond lengths are 1.94 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. O2- is bonded in a trigonal planar geometry to one Li1+ and two H1+ atoms.
