摘要
Fe[((py)im-C16)(3)](BF4)(2) (1) and Fe[((py)imH)(3)](BF4)(2) (2), the Iron(II) compounds with C16 long alkyl chain appended (py) imH and unmodified (py) imH [(py) imH = 2-(2-pyridyl)imidazole] have been synthesized and characterized by NMR, IR spectra and elemental analysis. For containing C16 long alkyl chain, complex 1 exhibits the liquid crystalline property around room temperature. The magnetic study suggests that 1 exists only in low spin state but 2 exhibits gradual spin crossover behavior. These observation suggests the possibility for synchronizing liquid crystallinity and spin crossover behavior of (py)imH complex in near future. (C) 2016 Elsevier B.V. All rights reserved.
