Lithium Chromate, Li₂CrO₄.2H₂O

Lithium Chromate, Li₂CrO₄.2H₂O, forms slightly soluble reddish-brown rhombic prisms:

a:b:c = 0.662:1:0.446.

The following double chromates have been described: LiNa₃(CrO₄)₂.6H₂O (ditrigonal, bipyramidal), and (NH₄)LiCrO₄ (yellowish-brown needles).

Lithium Dichromate, Li₂Cr₂O₇.2H₂O, forms dark brown, almost black crystals, fairly soluble in water.
