Structural characterization of nitrosodicyanomethanide and dicyanamide complexes of copper(II), nickel(II) and cobalt(II) with imidazole and 1-methylimidazole. X-ray crystallographic evidence of unusual nitrosodicyanomethanide O-bonding in Cu{ONC(CN)2}2 (1-methylimidazole)4

Low-dimensional compounds containing cyanido groups. Part XXXI. First simultaneous nucleophilic addition of water and ethanol to dicyanonitrosomethanide anions in the presence of Co(II)

“…There are peaks appearing at 1450 and 1415 cm À1 , which could be attributed to v as (ONC) and v s (ONC) vibrations, respectively, arising from the presence of nitroso groups. Acnm and cenm ligands are proved also by d(N@O) vibrations observed at 771 cm À1 [26]. The most characteristic bands of complex 1 exhibit no significant differences from those in similar complexes [7,9].…”

Electrochemical, Transport, and Spectroscopic Properties of 1-Ethyl-3-methylimidazolium Ionic Liquid Electrolytes Containing Zinc Dicyanamide

“…It has been previously shown that shifts to higher wavenumbers for the dca − vibrations generally correspond to binding of the anion to a metal center. 19 Therefore, it is proposed here that the growth of this new peak at 1369 cm −1 , coupled with the loss of intensity of the peak at 1308 cm −1 , corresponding to free dca − , indicates that free dca − in solution is solvating Zn 2+ to create a new complex anion. This behavior is mirrored by the ν(CN) peak of dca − (Figure 8b).…”

“…The ATR spectra of [emim][dca] containing 3 wt % H 2 O and increasing concentrations of Zn(dca) 2 in the region 3500–550 cm –1 are displayed in Figure . Assignments of the peaks can be found in Table , which were allocated with guidance from the studies of Jensen et al, MacFarlane et al, and Hvastijova et al…”

High Zn Concentration Pyrrolidinium-Dicyanamide-Based Ionic Liquid Electrolytes for Zn2+/Zn0 Electrochemistry in a Flow Environment

“…In addition, the band at 2127 cm –1 shifts to higher frequency with increasing Zn 2+ concentration. In the literature, it has been shown that shifts to higher wavenumbers for [dca] − vibrations are usually because of the stronger binding of the anion to the metal center . It is possible that the shift in the 2167 cm –1 band to a lower frequency with increasing Zn­(dca) 2 concentration is because of [dca] − acting as a bridging ligand between two Zn 2+ ions, implying the existence of larger complex ions of Zn 2+ .…”
