packing. Despite this variation, there is still a strong correlation of alkylchain length with the inter-tape spacing in a single direction in the crystal. This correlation is strongest at ambient temperature where the longer chains are highly disordered and extended. We observe an “odd-number carbon” effect where bis-N-propyl 1b and bis-N-pentyl 1d derivatives undergo a structuralphase transition with
