Abstract
The synthesis and characterization of new spin-crossover pyrazolato bridged dinuclear [{FeII(NCS)(py)}2(μ-bpypz)2] and the corresponding cyanotrihydroborato-κN complexes are described together with the X-ray crystal analysis of the latter in both the high-spin and low-spin states as well as the variable temperature magnetic susceptibility and/or Mössbauer spectra demonstrating the spin-crossover which exhibits an one-step process, but not a two-step one characteristic of the known bpym bridged dinuclear complexes.Keywords
