About Robinsonite
Formula:
Pb4Sb6S13
Colour:
Lead-gray
Lustre:
Metallic
Hardness:
2½ - 3
Specific Gravity:
6.7
Crystal System:
Monoclinic
Name:
Named in 1951 by Leonard Gascoigne Berry, Joseph John Fahey, and Edgar Herbert Bailey in honour of Stephen Clive Robinson (12 September 1911, Pincher Creek, Claresholm Census Division, Alberta, Canada - 13 September 1981, Saanichton, Capital Regional District, British Columbia, Canada), Canadian mineralogist, Geological Survey of Canada, and former Professor of Mineralogy, Queen’s University, Kingston, Ontario. Robinson synthesized the compound in 1947 (Robinson, 1948) before the mineral was found in nature.
The structure as in case of, e.g., boulangerite, jamesonite, and zinkenite, comprises interconnected SbS3 groups.
