The first spin-crossover cluster helicate [{Fe^II(μ-bpt)₃}₂Fe^II₃(μ₃-O)][Fe^II₂(μ-Cl)(μ-bpt)(NCS)₄(H₂O)]·2H₂O·C₂H₅OH [Hbpt = 3,5-bis(pyridin-2-yl)-1,2,4-triazole] was reported, in which one spin-crossover unit and one low-spin triple-stranded [Fe^II(bpt)₃]⁻ unit wrapped a rare planar [Fe^II₃(μ₃-O)]⁴⁺ core to form a bis(triple-helical) cation with trigonal-bipyramidal topology. The origin of different magnetic behaviors of two [Fe^II(bpt)₃]⁻ units could be ascribed to their different intermolecular interactions.
