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 (CH 3 CN) 2 ]X 2 · 2CH 3 CN (X = BF 4 – , ClO 4 – ) 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‐triazolyl) 4 (CH 3 CN) 2 ‐type core also exhibit thermally induced spin crossover.
