THE CRYSTAL STRUCTURE OF ORPIMENT (As2S3) REFINED

Mineralogical Journal, 1954
The crystal structure of orpiment, AS2':33, was refined by the Fourier syn. thesis. The unit cell has the dimensions, a=11.46 A, b=9.57 A, c=4.22 A ane ~=90.5°, containing four AS2':33. The space group is dh-P2t!n. The structun is essentially the same as one described earlier.
