Chromium Orthoantimonichloride, CrSbCl₈

Chromium Orthoantimonichloride, CrSbCl₈.10H₂O, was obtained by Weinland and Feige in the form of grey hygroscopic plates, but Pfeiffer obtained it as dark green crystals, and showed that it was not a derivative of the ortho-acid, but should be formulated thus:

[SbCl₆][Cr(OH₂)₄Cl₂].6H₂O.
