Materials Data on TeH14C2(NO2)4 by Materials Project

Abstract

(CO(NH2)2)2Te(OH)6 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight urea molecules and four Te(OH)6 clusters. In each Te(OH)6 cluster, there are three 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 1.00 Å. In the second H1+ site, H1+ is bonded in a distorted single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. Te6+ is bonded in an octahedral geometry to six O2- atoms. There is four shorter (1.94 Å) and two longer (1.98 Å) Te–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one H1+ and one Te6+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one H1+ and one Te6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one H1+ and one Te6+ atom.
