摘要：

The synthesis and characterisation of the complex [Fe-II(L)(2)]-(ClO4)(2) [L = S-(4-{[2,6-(Dipyrazol-1-yl)pyrid-4-yl]ethynyl}phenyl) ethanethioate] carrying both a spin-transition core and acetyl-protected terminal thiol groups is described. The compound exhibits a reversible, thermally driven solid-state spin transition at 277 K with a hysteresis loop of ca. 8 K. The unique combination of the bistable spin-transition property with thiol anchoring groups sets the basis for the investigation of the spin-transition switching phenomenon at a single-molecule level.
