Popis:	Equimolar mixtures of pyridine (Py) with para-halotetrafluoropyridine (BrTFP and ITFP) were investigated by VT-diffusion NMR experiments. The formation of a halogen-bond-stabilized ITFP·Py complex was detected upon cooling a solution in methylcyclohexane-d14 to 260 K; this allows monitoring a halogen-bond-driven aggregation process preceding crystallization in solution.
