Ferromagnetic spin interaction in a crystalline molecular complex formed by inter-heteromolecular hydrogen bonding: a 1 : 1 complex of phenyl nitronyl nitroxide radical and phenylboronic acid

Abstract

A crystalline molecular complex derived from phenyl nitronyl nitroxide and phenylboronic acid exhibits a ferromagnetic spin interaction (J=+0.65 K) below 30 K: X-ray analysis reveals the crystal structure to be constituted of a one-dimensional array of two component molecules linked alternately by the NO ⋯ HOB hydrogen bond.
