N2 - Molecular and crystal structures of mononuclear lanthanide (Ln) compounds with the 3,6-di(tert-butyl)-1,2-benzoquinone (SQ) radical anion of the composition [Ln(SQ)3(THF)2] (Ln = Pr, Nd, Eu, Tb, Dy), [Ln(SQ)3(Q)], (Ln = Gd, Eu; Q – 3,6-di(tert-butyl)-1,2-benzoquinone), [La(SQ)3(Q)(THF)], [CeIV(SQ)4], [NaLn(SQ)4(THF)3]·0.25C6H14 (Ln = Gd, Tb), [NaLn(SQ)4(Q)(THF)] (Ln = La, Pr) are determined. The study of the magnetic properties of isolated heterospin solid phases reveals that intramolecular antiferromagnetic exchange interactions between unpaired electrons of SQ moieties dominate in them. At T≤2 K [Dy(SQ)3(THF)2] exhibits the properties typical of a metamagnetic compound.
