Abstract :
The green basic 3 Valence H3O+Cr3(SO4)2(OH)6, is a hydrated sulphate of chromium related to Alunite - Yarosite groups. In this research, H3O+Cr3(SO4)2(OH)6 was prepared and the resulted crystal was characterized through chemical analysis and X-ray methods. The crystal system is hexagonal with parameters of a0 = 7/241 A,
C0 = 17/073 A. The principal X-rays of powder diagram are:
5/671(62). 5/029(100), 3/073(93), 3/043(96), 1/805(46) A
