The order and disorder in quasi-one-dimensional organic conductors is reviewed from a structural point of view. The qualitative features are discussed of the diffuse scattering and of superstructure reflections. The possibilities are considered to obtain structural information from a quantitative analysis of the diffuse scattering. Two examples are presented in detail. For C1TET-TTF(AuI2)0.8 it is shown that the partially ordered AuI2 substructure can be determined from the maxima within the diffuse sheets. For (Perylene)Co(mnt)2, a quantitative description of the first-order satellite reflections requires a saw-tooth shaped modulation function of large amplitude (0.7 A).
