Hi. This is a Wikipedia article https://en.wikipedia.org/wiki/Oxalatonickelate. There are quite interesting compounds, especially cobalt, manganese and cadmium. But nothing is
written about their synthesis. I'm doing sodium salt now, but I do not think it will come out. what do you think?

I'm skeptical. There are dozens of articles by a chemist called N. Deb that, in my opinion, are also a good example of poor publishing standards. I
myself dowloaded around 19 of them where he prepares so called "mixed oxalates" of the formula M[M(Ox)2] and none of them contains an actual
procedure, they just keep referencing to other articles of the same author without a definite procedure, just "mix two solutions".
I've tried a couple syntheses and nothing decent comes out. If you want a textbook example of lousy research, this is it.
In the file names Co,Ni indicates that it's the nickeloxalate, cobalt salt. But they are basically copy-pasted, so you just need to download one of
them.

I downloaded all the files, but unfortunately none opened.

Weird, they work fine with me... Just search on Scholar "Deb oxalato decomposition" and you will find a lot of them.

Thank you Valeg.

I've never even managed to make sodium bis(oxalato)nickelate- I just get nickel oxalate precipitating out, and refusing to do anything else.
Sodium and potassium bis(oxalato)cuprate, on the other hand, are very easy to make, and form nice crystals.

Exactly as you said, DraconicAcid. I tried a couple of those "procedures" by Deb but I think all that comes out is the plain metal oxalate. Lousy
publications imo
