Schoenfliesite

Schoenfliesite

  • Named in 1971 by George T. Faust and Waldemar T. Schaller in honor of Arthur Moritz Schoenflies ( 17 April 1853 – 27 May 1928) Professor of Mathematics, University of Frankfurt. Schoenflies’ researches in group theory and topology resulted in his proof of the 230 space groups.
  • Formula: MgSn(OH)
  • Space group: Pn-3 (No. 201)
  • Crystal system: cubic
  • Crystal class: m-3
  • Lattice parameters: a = b = c = 7.7449(4) Å, α = β = γ = 90°
