Sodium potassium tris(oxalato) ferrate

Formula: K5Na[Fe(C2O4)3]2 Sodium potassium tris-oxalato ferrate

One of the most interesting crystals: have deep green color, beautiful highly symmetric shape and stable on air. Unfortunately, I was not able to prepare aluminium analog: Na and K alumooxalates just crystallized separtely.
