I am aware of the (pictured) structure of $\ce{[Co(en)3]^3+}$, but what are the physical properties of this ion? Namely, what is its colour? 




[Co(en)3]Cl3 was important in coordination chemistry for its stability and stereochemistry and has been isolated as yellow, golden, needle like crystals. It is also described as a yellow, orange solid, soluble in water. The racemic complex is commonly obtained as the di or tri-hydrate although other hydrated forms are known.(Ref:Wikipedia)


The computed physical properties and other chemical data are well documented on @pubchem.
