The crystal structure of TlFeSe2 and TlFeS2 (synthetic raguinite)

Abstract

TlFeSe2 is monoclinic, space groupC2/mC 2h 3 ,a=11.973 Å,b=5.490 Å,c=7.110 Å, β=118.2°,Z=4.

TlFeS2 is isotypic witha=11.636 Å,b=5.304 Å,c=6.799 Å, β=116.7°.

The crystal structure of TlFeSe2 has been determined from single crystal diffractometer data. Isotypy of the sulfide has been confirmed from powder diffraction data. The crystal structure containing infinite linear chains of edgesharing FeX4-tetrahedra, and its relationship to the thio- and selenoferrates of the alkali metals are discussed. The mineral raguinite is very probably isotypic to synthetic TlFeS2.
