The bistability of multiple physical properties driven by external stimuli in a solid is a desired prerequisite for its application in memory devices with convenient data readout. We present a pathway for thermal bistability detectable in four physical properties: magnetic, light absorption, second-harmonic generation (SHG), and dielectric. We report a novel heterometallic (TBA){[Fe(phIN)][Re(CN)]} ⋅ (phIN) (1) (TBA=tetrabutylammonium cation, phIN=phenyl isonicotinate) cyanido-bridged chain material.

Mono-lanthanide compounds, K{Ln(HO)[Ru(CN)]}·HO (, Ln = La, = 3, = 1.2; , Ln = Ce, = 3, = 1.
