... = 20.626(1)Å] contains 2 formula units, which were found by site-occupancy refinement to be (K,Na) 5.68 (Fe,Cu,Ni) 20.27 S 26 (S,Cl) 0.93 . The structure is closely related to those of the cubic minerals pentlandite and djerfisherite. All three minerals have cubic close-packed sulfur layers, which...

..., Kola Peninsula, USSR. The electron microprobe analyses have established that the correct formula is KFe 2 S 3 instead of K 3 Fe 9 S 14 , as originally proposed. We compare new electron microprobe analyses of djerfisherite from the two localities and show that these djerfisherites do not contain...
