Abstract

Incorporating chiral organic ligands into cyanido-bridged FeII-NbIVassemblies synthesized chiral spin-crossover complexes, FeII2>[NbIV(CN)8](L)8·6H2O (L =R-,S-, orrac-1-(3-pyridyl)ethanol:R-FeNb,S-FeNb, orrac-FeNb). Rietveld analyses based on a racemic complex ofrac-FeNbindicate that the chiral complexes have a cubic crystal structure in theI213 space group with a three-dimensional cyanido-bridged FeII-NbIVcoordination network. All the complexes exhibit spin crossover between the high-spin (HS) and the low-spin (LS) FeIIstates without thermal hysteresis. Chiral complexes ofR-FeNbandS-FeNbshow second harmonic generation (SHG) due to their non-centrosymmetric structure. TheI213 space group provides second-order susceptibility tensor elements ofχxyz,χyzx, andχzxy, which contribute to SHG. The temperature-dependent second harmonic light intensity change is due to spin crossover between FeIIHS>and FeIILS.
