FT-IR Spectroscopic Study of M(Cyclopentanone)2Ni(CN)4 Complexes (M = Ni, Cd and Co)

Cyclopentanone-tetracyanonickel complexes, given by the general formula of M(cyclopentanone)2Ni(CN)4 (M = Ni, Cd and Co), were obtained for the first time. The similarities of the observed spectra with Hofmann-type complexes indicate that the obtained compounds are new examples of Hofmann-type complexes. - PACS: 33.20.Ea, 33.20.Tp

FT-IR Spectroscopic Study on Some 4-(3-Cyclohexen-1-yl)pyridine Metal(II) Tetracyanonickelate Complexes

New Hofmann-type complexes in the form of M(4-Chpy)2Ni(CN)4 [where 4-Chpy = 4-(3- cyclohexen-1-yl)pyridine and M = Ni, Co] were prepared in powder form, and their infrared spectra are reported in the range of 4000 - 400 cm−1. The spectral findings suggest that these compounds are similar in structure to the Hofmann-type complexes, and their structure consists of polymeric layers |M-Ni(CN)4|∞ with the 4-(3-cyclohexen-1-yl)pyridine molecule bound to the metal atom (M).

IR Spectroscopic Study of M(Benzoic Acid)2Ni(CN)4·(1,4-Dioxane) Clathrate (M = Ni, Cd and Co)

In this study, clathrate of benzoic acid-tetracyanonickel, given by the formula M(benzoic acid)2Ni(CN)4・(1,4-dioxane) (M = Ni, Cd and Co), is obtained for the first time through chemical methods. The similarities of the observed spectra indicate that the obtained clathrate of benzoic acidtetracyanonickel is a new example of Hofmann-type clathrates. - PACS numbers: 33.20.Ea, 33.20.Tp

FT-IR Spectroscopic Study of M(Benzoic Acid)2Ni(CN)4 Complexes (M = Ni, Cd, Co and Mn)

Complexes of M(benzoic acid)2Ni(CN)4 (M = Ni, Cd, Co and Mn) are obtained for the first time. The observed spectra indicate that the obtained complexes are new examples of Hofmann-type complexes. -PACS NO: 33.20.Ea, 33.20.Tp
