The solvothermal reactions of 1,4-benzenedisulfonic acid, H2BDS, with suitable salts of manganese, iron, and cobalt led to the new disulfonates M(BDS)(NMP)3 (M = Mn, Fe, Co), when N-methylpyrrolidone (NMP) was used as the solvent. The isotypic compounds crystallize with triclinic symmetry (P, Z = 2; M = Mn: a = 916.84(3) pm, b = 965.57(3) pm, c = 1437.87(5) pm, α = 95.297(2)°, β = 97.834(2)°, γ = 92.576(2)°, R1/wR2(I0 > 2σ(I0)) = 0.0300/0.0701; M = Fe: a = 911.98(5) pm, b = 960.75(5) pm, c = 1432.41(8) pm, α = 94.951(2)°, β = 98.050(3)°, γ = 92.029(2)°, R1/wR2(I0 > 2σ(I0)) = 0.0238/0.0689; M = Co: a = 911.3(1) pm, b = 959.5(1) pm, c = 1428.6(2) pm, α = 94.791(5)°, β = 98.229(5)°, γ = 91.873(6)°, R1/wR2(I0 > 2σ(I0)) = 0.0264/0.0684). In the crystal structure, the M2+ ions (Mn2+, Fe2+ and Co2+) are in octahedral oxygen coordination of three monodentate disulfonate groups and three NMP molecules. The disulfonate groups link the metal ions into infinite layers. Thermoanalytical investigations showed that the desolvation of the compounds occurred in a temperature range between 50 °C and 330 °C. The solvent free sulfonates showed remarkable high stabilities up to nearly 500 °C. The thermal behaviour was investigated by DSC/TG measurements and X-ray powder diffraction.
