The conversion from a [2 + 2] nested double-helical column, {[Mn2(ptptp)(suc)(H2O)2]路1.5H2O}n (1), to a cationic spiral staircase, {[Mn2(ptptp)(suc)0.5(H2O)3]路Br路0.5H2O}n (2), has been achieved through ionic liquid anion stimulations under solvothermal conditions. The conversion does not change the antiferromagnetic interactions.
