Dihypoiodites stabilised by 4-ethylpyridine through O-I-N halogen bonds.

Four bis(O–I–N) compounds have been synthesised from various dihypoiodites and 4-ethylpyridine. The compounds were characterised in both the solution and solid states by NMR spectroscopy (1H, 15N), X-ray diffraction, and computational calculations.
