“…In the resulting complexes, the A1g cyano stretching mode is observed at 2182 cm -1 (for Co-Ni-ampy) and 2184 cm -1 (for Ni-Ni-ampy) but B1g cyano stretching mode is not observed. In the Raman spectra of the complexes, the A1g mode shifted to higher wavenumbers around 23 cm group in the complexes are found to be similar to those of cyano-bridged complexes [32,33]. According to the obtained spectroscopic results, it was found that the ampy ligand in complex Co-Niampy coordinate to the metal atoms (Co and Ni) via the pyridine ring nitrogen and amino nitrogen atoms, whereas the ampy ligand in complex Ni-Ni-ampy coordinates to the metal (Ni) via the pyridine ring nitrogen atom.…”

New cyano-bridged polymeric complexes formulated as [Co(H2O)(ampy)Ni(CN)4]•H2O and [Ni(ampy)2Ni(CN)4]•H2O (ampy = 3-aminomethylpyridine: abbreviated henceforth as Co-Ni-ampy and Ni-Ni-ampy) have been obtained in powder form and characterized by vibrational (infrared and Raman) spectroscopy, thermal and elemental analyses. In previous study, structure of complex [Cd(NH3)(ampy)Ni(CN)4]n (Cd-Ni-ampy) was determined by single crystal X-ray diffraction methods. In this complex, the coordination environment of the Cd(II) ions are distorted octahedral geometry, whereas around the Ni(II) center is pyramidal. The spectral features suggest that Cd-Ni-ampy with Co-Ni-ampy are similar to each other and the ampy ligand is coordinated to metal ions as bidentate ligand. In addition, complex Ni-Ni-ampy is similar in structure to the Hofmann type complexes and its structure consists of polymeric layers of │Ni-Ni(CN)4│∞ with the ampy ligand bounded to the nickel(II) atom. Thermal stabilities and decomposition products of the complexes were investigated using TG, DTG and DTA curves in the temperature range of 30-700 °C in the static air atmosphere.

“…Upon the introduction of LiTFSI, the bands, belonging to C−H in the DMIm ring (3104 and 3132 cm −1 in FTIR; 3098 and 3120 cm −1 in Raman), undergo a significant redshift (Figure S4). Meanwhile, the bands at 2994 and 2948 cm −1 in FTIR for the stretching of CH 3 in DMIm experience significant blueshift and redshift, respectively [8b, 9] . Moreover, the band's intensity at 3010 cm −1 in Raman for the stretching of CH 3 weakens significantly (Figure S4).…”

“…Fourier‐transform infrared (FTIR) and Raman spectroscopy were used to analyze the formation mechanism of DEEs (Figure 1b). The FTIR and Raman peaks at 920 cm −1 in pure DMIm correspond to the N=C stretching [8b, 9] . After introducing LiTFSI, the band at 920 cm −1 moves to 937–933 cm −1 for the DEE‐1 : 1, 1 : 2, and 1 : 4, indicating the strong interaction of N=C group with the Li + ions.…”

As emerging eutectic mixtures, deep eutectic electrolytes (DEEs) show unique properties for Li-metal batteries (LMBs). However, the limited choice and inferior electrode compatibility hinder their further development in LMBs. Herein, we report a new 1,2dimethylimidazole (DMIm)-based deep eutectic gel polymer electrolyte induced by LiÀ N interaction. We demonstrate that incorporating electron-withdrawing polyvinylidene difluoride (PVDF) polymer into the DMIm-based DEE changes the coordination environment of Li + ions, leading to a high transference number of Li + ions (0.65) and superior interface stability between the electrolyte and Li anode. The deep eutectic gel polymer electrolyte exhibits excellent non-flammability, high ionic conductivity (1.67 mS cm À 1 at 30 °C), and high oxidation voltage (up to 4.35 V vs. Li/Li + ). The Li j j LFP cell based on the newly developed deep eutectic gel polymer electrolyte can achieve superior long-term cycling stability at a wide range of rates.

Since the discovery of Hofmann clathrates of inorganic cyanide bridged coordination polymers (Hofmann‐type CN‐CPs), extensive research is done to understand their behavior during spin transitions caused by guest molecules or external stimuli. Lately, research on their nanoscale architectures for sensors and switching devices is of interest. Their potential is reported for producing advanced functional inorganic materials in two‐dimensional (2D) morphology using a scalable solid‐state thermal treatment method. For instance, but not restricted to, alloys, carbides, chalcogenides, oxides, etc. Simultaneously, their in situ crystallization at graphene oxide (GO) nanosheet surfaces, followed by a subsequent self‐assembly to build layered lamellar structures, is reported providing hybrid materials with a variety of uses. Hence, an overview of the most recent developments is presented here in the synthesis of nanoscale structures, including thin films and powders, using Hofmann‐type CN‐CPs. Also thoroughly demonstrated are the most recent synthetic ideas with the modest control over the size and shape of nanoscale particles. Additionally, in order to create new functional hybrid materials for electrical and energy applications, their thermal decomposition in various environments and hybridization with GO and other guest molecules is examined. This review article also conveyed their spin transition, astounding innovative versatile adhesives, and structure features.
