Abstract

The photomagnetic properties of two series of spin-crossover solid solutions, [Fe(1-bpp)(2)](x)[Ru(terpy)(2)](1-x)(BF4)(2) and [Fe(1-bpp)(2)](x)[Co(terpy)(2)](1-x)(BF4)(2) (1-bpp = 2,6-bis[pyrazol-1-yl]pyridine), have been investigated. For all the materials, the evolution of the T(LIESST) value, the high-spin -> low-spin relaxation parameters and the LITH loops were thoroughly studied. Interestingly in the Fe : Co series, along the photo-excitation, cobalt ions are concomitantly converted from low-spin to high-spin states with the iron centres, and also fully relax after light excitation.
