A novel 1D hybrid salt (MQ)[CuBr2](infinity) (MQ = N-methylquinoxalinium) is reported. Structural, spectroscopic and magnetic investigations reveal a minimal Cu-II doping of less than 0.1%. However it is not possible to distinguish Cu-I and Cu-II. The unusually close packing of the organic moieties and the dark brown colour of the crystals suggest a defect electronic structure.
