Two polymorphs of a chiral conductor formulated (BEDT-TTF)3NaCr(C2O4)3·CH3NO2 have been crystallised from a solution containing the racemic anion tris(oxalato)chromate(III). In the presence of (R)-(−)-carvone the electrocrystallisation of Na3Cr(C2O4)3 with BEDT-TTF and nitromethane yields two products: hexagons crystallising in the space group P212121 (I) and needles in the space group P21 (II). Single crystal electrical transport measurements show semiconducting behavior for both salts.
