Vibrational spectra, powder X-ray diffractions and physical properties of cyanide complexes with 1-ethylimidazole

New cyanide-bridged heteronuclear polymeric complexes M(II)/Ni(II) (M = Fe, Mn and Co) with 1-ethylimidazole were synthesized and characterized. The structures of these complexes were elucidated using vibrational spectra and powder X-ray diffraction patterns with the peak assignment to provide a better understanding of the structures.
