Permingeatite, Cu₃SbSe₄, a new selenide of the luzonite-germanite group was found in Predborice, Bohemia, Czechoslovakia. Tetragonal, D¹¹/2d-I[-4]2 m, with a = 5.63, c = 11.23 Å, c/a = 1.994, Z = 2, dₓ = 5.82. The strongest lines in the powder pattern are : 3.251 (10) ; 1.986 (9) ; 1.697 (8) ; 1.290 (6) ; 1.148 (7). Microprobe analysis gave : Cu — 30.7 ; Sb — 17.4 ; As — 1.5 ; Se — 50.4 ; total 100.0. In polished section it is light brownish pink, strongly anisotropic with mono-synthetic twins. Microhardness (Vickers) : 234 kg/mm². Reflectivity (%) : 28.8-30.4 (420 nm), 27.9-29.7 (500 nm), 24.5-25.2 (600 nm), 23.8-25.4 (640 nm). It occurs with berzelianite, hakite, eskebornite, umangite, naumannite, clausthalite, ferroselite, klockmannite, ...
