| Popis: | 57Fe Mössbauer spectroscopic results on the 2D Hofmann-like coordination polymer Fe(4-Clpy)2Ni(CN)4 (sample 1) indicate that iron(II) ions are in a high spin state both at R.T. and T = 80 K, showing that the compound exhibits no spin crossover (SCO) behavior. Mössbauer spectra at R.T. and T = 80 K show one major doublet which corresponds to the HS1 is due to high spin iron(II) sites coordinated by four N atoms of cyano groups and two N atoms of 4-Clpy ligand in the sample 1. Two minor doublets coexisted in sample 1. One minor doublet with a large quadrupole splitting can be explained by the presence of defects in the coordination polymer frameworks. Another minor doublet is with a small quadrupole splitting, indicating the presence of iron(III) high spin species or iron(II) low spin species.
