Formula:
Pd8Sb2.5As0.5
Colour:
Brassy yellow
Lustre:
Metallic
Hardness:

Crystal System:
Trigonal
Name:
For John Beaver Mertie, Jr. (22 January 1888, Baltimore, Maryland, USA - 7 December 1980, Rockville, Maryland, USA), was geologist with the United States Geological Survey. He spent 30 years geologically mapping Alaska. For many years it was named mertieite-II; it was renamed to mertieite in 2022.
Isotypic with synthetic Pd8Sb3.

Isostructural with vadlazarenkovite and may be understood as its (SbAs)-analogue.
