Materials Data on TcH4NO4 by Materials Project
TcO4NH4 is Silicon tetrafluoride-derived structured and crystallizes in the tetragonal I4_1/a space group. The structure is zero-dimensional and consists of four ammonium molecules and four TcO4 clusters. In each TcO4 cluster, Tc7+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Tc–O bond lengths are 1.74 Å. O2- is bonded in a single-bond geometry to one Tc7+ atom.
