Materials Data on AsSe3(ClF2)3 by Materials Project
SeAsF6SeClSeCl2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four chloroselenurane molecules, four selenium molecules, four selenium dichloride molecules, and four AsF6 clusters. In each AsF6 cluster, As3+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of As–F bond distances ranging from 1.77–1.80 Å. There are six inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one As3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one As3+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one As3+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one As3+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one As3+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one As3+ atom.
