Crystalline Cs salts with the difurazanopyrazine radical anion are synthesized: Cs(L•)(H2O)2-I, Cs(L•)(H2O)2-II, Cs2(L•)2(HL•)(H2O), Cs3(L•)3(L••)2(H2O)3. In the solid phase, Cs ions are surrounded by water molecules and are located between the stacks of difurazanopyrazines, forming a framework. The study of the structure and magnetic properties of the compounds shows that Cs(L•)(H2O)2-I represents a metastable phase that transforms into Cs(L•)(H2O)2-II on cooling and differs from the initial compound by a shift of radical anions relative to each other in the stacks. It is found that in Cs(L•)(H2O)2-II there is strong antiferromagnetic exchange between paramagnetic centers.
