Electrochemical Growth of Highly Conducting Inorganic Complexes

The formation of single crystals of highly conducting inorganic complexes, for example, K(2)Pt(CN)(4)X(0.3) . 3H(2)O (X = Cl, Br), K(1.75)Pt(CN)(4) . 1.5 H(2)O, or K(1.64)Pt(O(2)C(2)O(2)) . 2H(2)O, has been effected via electrochemical growth from concentrated aqueous solutions of potassium tetracyanoplatinate(II) and potassium bis(oxalato)platinate(II).
