Abstract
AsTe2Se4F9AsF3 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is two-dimensional and consists of four trifluoroarsine molecules and two AsTe2Se4F9 sheets oriented in the (0, 0, 1) direction. In each AsTe2Se4F9 sheet, As5+ is bonded in an octahedral geometry to six F1- atoms. There are a spread of As–F bond distances ranging from 1.74–1.83 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 2-coordinate geometry to one Se+1.50- and two F1- atoms. The Te–Se bond length is 2.65 Å. There are one shorter (1.97 Å) and one longer (2.54 Å) Te–F bond lengths. In the second Te4+ site, Te4+ is bonded in a distorted single-bond geometry to one Se+1.50- and one F1- atom. The Te–Se bond length is 2.76 Å. The Te–F bond length is 2.07 Å. There are four inequivalent Se+1.50- sites. In the first Se+1.50- site, Se+1.50- is bonded in a 1-coordinate geometry to one Se+1.50- and one F1- atom. The Se–Se bond length is 2.41 Å. The Se–F bond length is 2.87 Å. In the second Se+1.50- site, Se+1.50- is bonded in a 5-coordinate geometry to one Te4+, two Se+1.50-, and two F1- atoms. The Se–Se bond lengthmore »
