Ferric Ammonium Oxalate (green crystals): CAS 14221-47-7
     (NH4)3Fe(C2O4)3 + 3 H2O Formula weight = 428.04

Ferric Ammonium Oxalate (granular): CAS 13268-42-3
     (NH4)3Fe(C2O4)3 + 3 H2O Formula weight = 428.04

Ferric Oxalate (anhydrous): CAS ??
     Fe2(C2O4)3 Formula weight = 375.74

Ferric Oxalate (scales/pearls): CAS ??
     Fe2(C2O4)3 + 6H2O Formula weight = 484.71

Unfortunately, I transferred my last reagent-grade FeOx to smaller
containers for preservation, so I don't have the CAS number handy.
Doubly unfortunately, I can't find it in any current chemical
catalogs, so knowing the CAS number may be academic.

Best regards,

Charles
