E. Hernandez et al., HYDROGEN-BONDS AS A CRYSTAL DESIGN ELEMENT FOR ORGANIC MOLECULAR-SOLIDS WITH INTERMOLECULAR FERROMAGNETIC INTERACTIONS, Angewandte Chemie, International Edition in English, 32(6), 1993, pp. 882-884
O-H ... O-N and H2C-H ... O-N hydrogen bonds determine the arrangement
of the stable radical 1 in the solid state. This leads to a system wi
th intermolecular ferromagnetic interactions still rare in solids comp
osed of exclusively organic compounds. The experimental findings are c
onsistent with properties for solid 1 predicted by MO calculations and
geometric considerations.
