摘要：

Bis(1,2,3-triazol-1-yl)methane (mbtr) was used to prepare 1D networks in which neighboring iron(II) ions are tethered by two semiflexible ligand molecules. [Fe(mbtr)(2)(CH3CN)(2)]X-2. 2CH(3)CN (X = BF4-, ClO4-) systems represent unique example of complexes that are based on monosubstituted 1,2,3-triazoles, in which four 1,2,3-triazole rings and two axially coordinated nitrile molecules form the first coordination sphere. Single-crystal X-ray diffraction and magnetic studies revealed that, in addition to homoleptic [Fe(1,2,3-triazol)(6)]-type core systems, complexes possessing the Fe(1,2,3-triazol-yl)(4)(CH3CN)(2)-type core also exhibit thermally induced spin crossover.
