Journal ArticleDOI
Direct two-step spin-crossover through [HS–HS]⋯[LS–LS] at the plateau in dinuclear diiron(II) complex [{Fe(NCBH3)(4phpy)}2(μ-bpypz)2]
Keisaku Nakano,Satoshi Kawata,Ko Yoneda,Akira Fuyuhiro,Takashi Yagi,Saburo Nasu,S. Morimoto,Sumio Kaizaki +7 more
TL;DR: The variable temperature magnetic susceptibility, X-ray crystallography, and IR and Raman spectra of a new dinuclear complex demonstrated the first two-step spin-crossover associated with a 1 : 1 mixture of high-spin pair [HS-HS] and low- spin pair [LS-LS] at the plateau.
Journal ArticleDOI
Substituent effect of the coordinated pyridine in a series of pyrazolato bridged dinuclear diiron(II) complexes on the spin-crossover behavior
TL;DR: There were found linear correlations of the spin-crossover temperatures Tc not only between the NCS and NCBH3 complexes with the corresponding substituted pyridines, but also between the Tc and the Hammett constants, supporting the electronic substituent effect of the coordinated pyridine rather than a steric effect.

Journal ArticleDOI
A steep one-step [HS-HS] to [LS-LS] spin transition in a 4,4'-bipyridine linked one-dimensional coordination polymer constructed from a pyrazolato bridged Fe(II) dimer.

TL;DR: The variable temperature magnetic susceptibility, X-ray crystallography, and Mössbauer and Raman spectra of a new dinuclear complex-based one-dimensional coordination polymer demonstrate a steep one-step [HS-HS] to [LS-LS] spin transition.
