Notes:
Crystals of TlAsSe2 have been grown in a single-zone furnace. Precession photographs show that the compound is monoclinic, space group P21/c. Data for the unit cell are: a = 6.26, b = 23.64, c = 12.33 Å; β = 106.5°; Z= 16, Dm = 6.19, Dx = 6.64 g cm−3 . An indexed powder pattern is given. In relation to its sulphur analogue TlAsS2 (the mineral lorandite), TlAsSe2 has a doubled unit cell in the direction of the unique axis.
