Materials Data on SiH18C2N8(OF3)2 by Materials Project

(CN4H7)2SiF6(H2O)2 is alpha Pu-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two aminoguanidinium molecules, two water molecules, and one SiF6 cluster. In the SiF6 cluster, Si4+ is bonded in an octahedral geometry to six F1- atoms. There is four shorter (1.72 Å) and two longer (1.73 Å) Si–F bond length. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Si4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Si4+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Si4+ atom.
