• solution was obtained via direct methods and refined [34] by full-matrix least-squares on F2, with hydrogens included in idealised positions. There is rotational disorder of a thiophene moiety in 28, where C10 and S4 occupy the same position in the ring with a site occupancy of 50%. Supplementary data for

• occupancy. Tetramer 9a does not suffer from this ambiguity; it is approximately an open dimer of Ci dimers with large θ of alternating sign. The molecules in the trimer and tetramer are unrelated by symmetry; Z' = 3 and 4 respectively. A comparison of the calculated stabilities of the sets of hydrogen-bound
