Abstract
Recently (Soria, D.B.; Aymonino, P.J. Spectrochim. Acta 1999, A55, 1243), we reported improved 13C NMR and IR and Raman spectra, as well as the TGA-DTA behavior of Na3[Fe(CN)5CO]·2H2O. We now report for the first time the structure of the anion obtained by x-ray diffraction (XRD) measurements performed with single crystals of the mixed Na16{[Fe(CN)5CO]4[Fe(CN)6]}··32H2O salt which crystallizes in the tetragonal I4/m space group, with a = 16.308(2), c = 15.418(2) Å, and Z = 2. The theoretical structure and the wave numbers corresponding to the normal modes of vibration of the [Fe(CN)5CO]3− (carbonylprusside) anion were calculated with DFT methods and compared with experimental results.
