Amine-Functionalized Spin Crossover Building Blocks.

ABSTRACT: Bistable spin crossover complexes such as [Fe{HB(pz)₃}₂] (pzH = pyrazole) show promise for sensor applications and electrically-controlled data storage units, but exploiting their potential hinges on their integration into a functional environment. We here present a system enabling such covalent post-functionalization steps in both symmetric and asymmetric patterns, based on the amine-functionalized complex [Fe{HB(4-NH₂pz)(pz)₂}₂], obtained by reduction of the nitro analogue. The building block aspects of [Fe{HB(4-NH₂pz)(pz)₂}₂] are showcased by its transformation into amide, imine and azo derivatives, which are structurally and magnetically characterized. All tris(pyrazolyl)borate complexes retain the
