The crystals under study are formed by low-spin or high-spin molecules of Fe(phen)$_{2}$(NCS)$_{2}$ (phen = 1,10-phenanthroline), Fe(btz)$_{2}$(NCS)$_{2}$ (btz = 5,5$^{\\prime }$,6,6$^{\\prime}$-tetrahydro-4\\textit{H},4$^{\\prime}$\\textit{H}-2,2$^{\\prime }$-bi-1,3-thiazine), and Fe(bpz)$_{2}$(bipy) (bpz = dihydrobis(1-pyrazolil)borate, and bipy = 2,2$^{\\prime}$-bipyridine). All molecular geometries are taken from the X-ray experimental data and assumed to be frozen.
