## Abstract The thermal variation of the dielectric constant in the spin crossover complex [Fe(bpp)~2~] [BF~4~]~2~ displays a 16 K large hysteresis loop centered around 178 K corresponding to the spin transition temperatures. Unexpectedly, the dielectric constant has a higher value in the low‐spin
The Miissbauer spectra of iron and cobalt fluoroborate hexahydrate show a change by a factor of two in the quadrupole interaction near 2%) K and 185 K, respectively, togtther with a sudden drop in resonance fraction. This behaviour is explained as a first order phase transition in which the axial pa
