Query: Can Cu(II) ions be doped into the crystal structure of potassium
  hydrogen tartrate?   The differing binding preferences of the hydrogen tartrate ligand (HC4H4O6)-
namely {\mu}7-octadentate mode for potassium ion and bidentate mode for cupric
ion rules out the doping (incorporation) of any Cu(II) ion into the crystal
structure of potassium hydrogen tartrate. Hence, the claim of growth of copper
doped potassium hydrogen tartrate viz. K0.96Cu0.04C4H5O6 by Mathivanan and
Haris, Indian J Pure App Phys 51 (2013) 851-859 is untenable.
