Merenskyite is a rare telluride / bismuthinide mineral with the chemical formula (Pd,Pt)(Te,Bi)
2
.[2][3] It is an opaque white to light gray metallic mineral that occurs as inclusions within other minerals such as chalcopyrite. It crystallizes in the trigonal crystal system.[2]

Merenskyite was first described in 1966 for an occurrence in the Merensky Reef of the Western Bushveld Igneous Complex, South Africa , and named for South African geologist Hans Merensky (1871–1952).[4]
