Synthesis and identification of the nickel dimethylformamide and thiocyanate [Ni (SCN) 2 (DMF) 4] complex by hydrothermal method

In this paper, we synthesized [Ni (SCN) 2(DMF)4] complex (DMF= N, N-dimethylformamide and SCN= thiocyanate) by hydrothermal method [1]. This complex characterized by single-crystal X-ray analysis (X-Ray), Fourier Transfer infrared (FT-IR) and UV-vis spectroscopy. The results of infrared spectroscopic studies showed stretching vibration of CN bond in the NCS ligand in the 2063 cm-1 region. Absorption spectra of complexes showed transitions in the UV-Vis region, which are related to the SCN and dimethylformamide (DMF) ligands. Low-intensity absorbing bands in the 400-800 area that are attributed to d-d metal doped metal ions in the complex. These delicate bands are the result of multiple to multiple transitions in d orbital. The d → d transfers of nickel are seen in the region of 800nm. The electron transfer in this region corresponds to 3A2g → 3T2g. Ni also contains 3A2g → 3T1g (F) and 3A2g → 3T1g (P) transfers [2]. The ORTEP diagram of the complex is shown in Figure 1.
