Electrocrystallisation of Highly Conductive Thia Adducts

Conductive adducts such as TTFX_n (X = halide) are more highly conductive when electrocrystallised galvanorather than potentiostatically. With the latter method, current-time behaviour is diagnostic of crystal quality, five different classes of behaviour and product being discernible. Mixed-halide TTF (I + Br)_n with n ～ 0.7 as in the monohalides, can be electrocrystallised. Electrode and cell configuration and conditions also govern crystal properties and accessibility of products. Thus, conical electrodes of 4mm diameter and 9mm height with a vertical wire as counter -electrode give the largest TTF (NO₃)_0.55 crystals

Higher temperature yields larger crystals.

Adduct compositions are sometimes governed by solvent.
