Can Cu(II) ions be doped into the crystal structure of potassium hydrogen tartrate?

Srinivasan, B.R.; Remesh, H. (Published online on arXiv)

The differing binding preferences of the hydrogen tartrate ligand (HC4H4O6)- namely mu7-octadentate mode for potassium ion and bidentate mode for cupric ion rules out the doping (incorporation) of any Cu(II) ion into the ...

Can zinc(II) ions be doped into the crystal structure of L-proline cadmium chloride monohydrate?

Srinivasan, B.R. (Spectrochimica Acta Part A-Molecular and Biomolecular Spectroscopy. 116; 2013; 635-638.)

The bivalent metals Cd(II) and Zn(II) exhibit different stereochemical requirements for the set of chloride and l-proline ligands, which precludes the doping of Zn(II) ions into the crystal structure of dichloro(l-prolin ...
