Abstract (in english)
   Jacutingaite, Pt2HgSe3, is a new platinum-group mineral discovered at the Caue iron-ore deposit, Itabira district, Minas Gerais, Brazil. Observed in a polished section, the mineral is about 50 ?m across and occurs on an aggregate of atheneite, potarite and hematite. The new mineral is partly altered to a Pt-O phase. Synthetic jacutingaite is megascopically grey in color, has a metallic luster and a grey streak. The mineral is brittle, with a very good {001} cleavage. The mineral is trigonal, space group P m1, with a 7.3477(2), c 5.2955(1) A, V 247.59(1) A3 and Z = 2. The crystal structure was solved and refined from the powder X-ray-diffraction data of synthetic Pt2HgSe3. Jacutingaite is isostructural with Pt4Tl2X6 (X = S, Se, or Te); no structural analogue is known as a mineral. Jacutingaite is structurally related to sudovikovite.
