This is the first report on the folding phenomenon of pyridazinone and triazinone dimers (1–5) bridged through an alkyl chain. Among them, direct evidence of conformational preference of 1, 2, and 5 was obtained through single crystal X-ray structures. However, prevalence of folded conformations was analyzed through theoretical investigation.
