Abstract

N(CH3)4CH2OHTeF6 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four formaldehyde molecules, four tetramethylammonium molecules, and four HTeF6 clusters. In each HTeF6 cluster, H1+ is bonded in a linear geometry to two F1- atoms. There is one shorter (0.99 Å) and one longer (1.43 Å) H–F bond length. Te2- is bonded in a 5-coordinate geometry to five F1- atoms. There are a spread of Te–F bond distances ranging from 1.91–2.17 Å. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Te2- atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Te2- atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Te2- atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one H1+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Te2- atom. In the sixth F1- site, F1- is bonded in a distorted water-like geometry to one H1+ and one Te2- atom.
