Growth of (Perylene) 2 [Pd(mnt) 2 ] crystals

The conditions for the growth of (Perylene)2 [Pd(mnt)2] crystals either by chemical oxidation and electrochemical routes are described. The electrocrystallisation is limited by close proximity of the oxidation potentials of the perylene donor and [Pd(mnt)2]− anion, and depending on the experimental conditions different morphologies can be obtained. (Per)2 [Pd(mnt)2] crystals obtained by elecrocrystallisation were found to be mainly of the β-polymorph with properties comparable to the Cu, Ni and Pt analogues previously described at variance with those obtained by chemical oxidation which are mainly of the α-polymorph .
