Dimethyl Sulfoxide in Inorganic Chemistry

Study of Nd Electrodeposition from the Aprotic Organic Solvent Dimethyl Sulfoxide

“…The spectra are presented in Figure 3 for the pure DMSO, 0.1 M NdCl 3 in DMSO, and 1 M NdCl 3 in DMSO. Dimethyl sulfoxide has a sulfonyl group and the normal absorption of the S=O bond occurs at 1050 cm −1 [13,14], as confirmed in Figure 3. Metals can bond to DMSO either through its oxygen or its sulfur [13,15].…”

“…Dimethyl sulfoxide has a sulfonyl group and the normal absorption of the S=O bond occurs at 1050 cm −1 [13,14], as confirmed in Figure 3. Metals can bond to DMSO either through its oxygen or its sulfur [13,15]. If the bonding is to the sulfur, the metal donates electrons from its π orbitals into an empty π orbital on the DMSO ligand, thereby increasing the S-O bond order.…”

“…It is strongly recognized that the complexation of cations in a solution plays an important role in the properties and characteristics of a potential electrolyte [12,13]. The next step of the study was to determine the state of Nd in the prepared solutions by Infra-Red spectroscopy.…”

“…Thus, if the metal is bonded to the DMSO at the sulfur, the frequency of the S=O absorption increases. If the bonding is to the oxygen of the DMSO, the metal forms a bond with one of the lone pairs on the oxygen and thereby withdraws electron density from the oxygen [13]. Therefore, the S=O bond order declines and the S=O absorption appears at a lower frequency.…”

Investigating the effect of solvent vapours on crystallinity, phase, and optical, morphological and structural properties of organolead halide perovskite films

“…This coordination ability can be as a monodentate ligand by donating a pair of electrons to the cations through atom of the S-O bond and also by hydrogen bonding. 48 Therefore DMF seems to be a weaker eld ligand compared to DMSO but stronger than acetone. For the aprotic solvents therefore, the solvent coordination ability follows the same trend as its Gutmann donor number.…”
