“…The frequency at 112 cm-1, observed also by Edgell4 and by Loss13 in the low-frequency infrared spectrum of liquid and solid Fe(CO)6, is now assigned to the vu mode (E' in Dsn symmetry); this agrees with the occurrence of a Raman line at the same frequency in the spectrum of the liquid complex.7 For the same reason and according to Edgell,11 the 75-cm-1 frequency has been attributed to the Pie mode; its corresponding Raman shift falls at 68 cm-1. 7 The remaining frequency at 104 cm-1 is therefore the vig mode (E"), having again a corresponding Raman line in the liquid spectrum.…”

“…The vibrational spectrum of iron pentacarbonyl has been widely studied, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] but extensive data on the crystal spectrum are yet not available. Two normalcoordinate analyses were published almost at the same time.…”

“…Nesse sentido, a possibilidade do grupo do Prof. Stammreich de excitar o espectro Raman com radiações de He (667,8 nm e 706,5 nm) foi fundamental porque Fe(CO) 5 é colorido e fotosensível. 7 A atribuição do espectro Raman indicou três modos atribuídos como estiramentos C-O (2 A 1 ' e 1 E'), três dobramentos de ângulo C -Fe-C (2 E' e 1 E") e sete modos de estiramento Fe-C ou dobramento de ângulo Fe-C-O (2 A 1 ', 3 E' e 2 E"). Portanto, ao comparar o número de modos normais de cada espécie de simetria e as correspondents atividades Raman, concluiu-se que a estrutura de Fe(CO) 5 é a bipirâmide trigonal (D 3h ).…”

“…Portanto, ao comparar o número de modos normais de cada espécie de simetria e as correspondents atividades Raman, concluiu-se que a estrutura de Fe(CO) 5 é a bipirâmide trigonal (D 3h ). 7 Uma ambiguidade análoga foi a motivação de um artigo póstumo de 1970 8 sobre a estrutura do íon pentacianidoniquelato(II) em solução aquosa. Stammreich e colaboradores 8 propuseram que a estrutura de…”

“…Following the previous vibrational mode assignments 29 30 , the observed Raman peaks of Fe(CO) 5 can be characterized into three groups, as summarized in Table S1 : (i) the C ≡ O stretching modes, ν s (CO), in the spectral region between 1800 and 2200 cm −1 , (ii) the Fe-CO stretching modes, ν s (Fe-CO), and Fe-C ≡ O bending modes, ν b (Fe-C ≡ O), between 350 to 650 cm −1 , and (iii) the C-Fe-C bending modes, ν b (C-Fe-C), below 300 cm −1 . Fe(CO) 5 has a bipyramidal structure with an Fe atom at the center and five carbonyls attached to the central Fe: three on the equatorial plane and two on the axial direction 31 .…”
