N1 - Funding Information:
One may expect better results if boronic acid itself is used as an inter-heteromolecular spincoupler. Despite of all efforts we could not obtaine molecular complexes of boronic acid with 1. It may be important to explore the hetero-component crystals including a radical species for better understanding the magneto-structural relations, since those diversify the bulk magnetic properties of radical species depending on the constituent component.

N2 - A crystalline molecular complex derived from phenyl nitronyl nitroxide (1) and phenyl boronic acid (2) exhibits a ferromagnetic spin interaction (J= +0.65 K) below 30 K: An X-ray analysis revealed the crystal structure constituted of one-dimensional array of two component molecules linked alternately by the NO-HO-B hydrogen bonds. The NO-HO-B-OH - ON linkage was suggested to act as a path for ferromagnetic spin coupling. An unusual formation of nitrosonium salt (3) was found in the reaction of 1 and BF3. Its molecular and crystal structures were determined.
