Studies of the spectra of copper dimethyl-glyoxime, nickel dimethylglyoxime and nickel ethylmethylglyoxime in various solvents

Structural and optical studies of evaporated bis-(dimethylglyoximato)nickel(II) thin films

“…The UV-absorption band has a high-wavelength shoulder at around 325 nm. The UV band is assigned as metal-to-ligand charge transfer band [16]. The UVpeak is typically more intense than the Vis-peak and the ratio of the absorbance of the UV-peak to that of the strongest Vis-peaks was about 2.0 for AM and 5.0 for CR, which reflects the influence of the crystal structure.…”

Synthesis of carbon nanotubes by pyrolysis of solid Ni(dmg)2

“…Nickel(II)dimethylglyoxime [Ni(dmg) 2 ], was prepared using a known procedure [23]. A solution of glyoxime (0.0129 mol) in ethanol (150 mL) was added to a warm (80 • C) aqueous solution of Ni 2+ (0.005 mol) (30 mL) (Nickel standard solution, Fluka) and the whole mixture was made alkaline with aqueous ammonia.…”

DFT Investigation of the Molecular Properties of the Dimethylglyoximato Complexes [M(Hdmg)2] (M = Ni, Pd, Pt)

“…Even though [Ni(Hemg) 2 ] has a shorter O ... O distance of 2.33 Å [18] compared with [Ni(Hdmg) 2 ] (2.40 Å or longer; Table S1) and probably stronger hydrogen bonding, the solubility is markedly higher. The poor solubility alongside the bright red colour is well-established as a probe for Ni II in elemental analyses [16,17,22,23]. Even without the H bonds, the geometry of the Pd II and Pt II derivatives would be square planar, due to the intrinsically strong ligand field of 4d and 5d metals, and the metal ... metal stacking planar, due to the intrinsically strong ligand field of 4d and 5d metals, and the metal ... metal stacking is facilitated for these two elements due to the larger size of their frontier d orbitals [9].…”
