Abstract: The first organic magnet based on a high-nitrogen framework of pyrazine-fused furazans Na(L^•−)(H₂O)₃ was found. A quantum-chemical study of M(L^•−)(H₂O)_n, where M = Li, Na, K, Rb, NH₄, revealed that exchange coupling energy between the neighboring radical anions proved highly sensitive to the motion of one L^•− relative to another.

Keywords: bis(furazano)pyrazine, sodium, potassium, rubidium, ammonium, stable radical, molecular magnet, McConnell’s exchange model.
