1850 J. D. Dana Syst. Mineral. (ed. 3) 547 At a high temperature the Sisserskite gives out osmium, but undergoes no further change.

1938 Mineral Abstr. 7 162 The natural alloys are divided into three groups: (1) iridium group with 0–35% Os, cubic; (2) nevyanskite with 35–50% Os; (3) sysertskite with 50–70% Os.

1963 Mineral. Mag. 33 714 Iridosmine for the hexagonal phase (with Nevyanskite and Sysertskite as varieties) and Osmiridium for the cubic phase.

1965 G. J. Williams Econ. Geol. N.Z. x. 155/1 In the other [fraction] consisting of flattened grains of light steel-grey colour, Os was found in excess of Ir, and the Ru proportion is higher—siserskite or ruthenian siserskite.

1973 S. E. Livingstone in J. C. Bailar et al. Comprehensive Inorg. Chem. III. xliii. 1165 Alloys of osmium and iridium occur in placer deposits. These are known as osmiridium or sysertskite—with less than 60% (usually ca. 50%) iridium and ca. 35% osmium—and iridosmium or nevyanskite—with over 60% (usually ca. 70%) iridium and ca. 20% osmium.
