“…Band assignments are listed in Table 1 for Cu-and Co-montmorillonite-DMSO complexes. As may be noted, these assignments are consistent with those made for DMSO in related phases (Forel and Tranquille, 1970;Cotton et al, 1960). The observed band locations for one of the symmetric C-H deformation modes of Co-and Cu-clay-DMSO complexes are 1318 and 1320 cm -1, respectively.…”

Abstract--The i.r. spectra (4000-1200 cm 1) are obtained for several homoionic montmorillonite films on which various amounts of dimethyl sulfoxide (DMSO) were adsorbed. Analyses of these spectra indicate that H-and natural-montmorillonite-DMSO complexes contain an intercalated layer of physisorbed DMSO while transition metal cation substitutedmontmorillonite-DMSO complexes possess both physi-and chemisorbed DMSO in their interlamellar spaces. The latter species involve coordination of DMSO molecules with the exchangeable cations by their oxygen atoms. Most of the interlamellar water is replaced by DMSO as the latter molecules penetrate the interlameUar spaces. Heat-treating transition metal cation substituted-montmorillonite-DMSO complexes at 120~ for 48 hr results in both the desorption of physisorbed DMSO and the retention of intercalated monolayers involving DMSO-transition metal cation coordination. A water-sensitive, reversible color change (tan to light purple) is produced by either desiccating over P~O.~ or heat-treating at 120~ the cobalt-montmorillonite-DMSO complex. Interpretation of the visible spectra suggests that Co2+-cations undergo changes from octahedral to tetrahedral coordination during desiccation or heating. Band assignments are made for the clay complexes using the assignments for related gases, liquids, and crystals.

“…A tentative assignment was carried out by comparison with the vibrational spectra of the free ligands, and of related complexes from the literature (10,(13)(14)(15). In general, the vibrational frequencies associated with the dmso and tbpy ligands are rather similar for both isomers; the main differences (Fig.…”

The reaction of cis- [RuCl,(dmso),] (dmso = dimethylsulfoxide) with 4-tert-butylpyridine (tbpy) in chloroform leads to the all cis (ccc) and the cis,cis,trans (cct) geometrical isomers of [RuCl,(S-dmso),(tbpy),]. The cct isomer exhibits a reversible cyclic voltammogram, ascribed to the RU"'"' redox couple with Ell, = 1.12 V versus SHE. The ccc isomer can be oxidized at Ell, = 1.27 V; however, the oxidized species undergoes a relaxation equilibrium, (K,,, = 1.59), involving the S-to-0 linkage isomerization of a coordinated dmso ligand (k,,, 1.9 s-I and kojS = 1.2 s-I). The isomerization reaction in the RU"' ccc isomer is discussed in terms of the competitive effects between the S-bound dmso and the tbpy ligands. DENISE 0 . SUVA et HENRIQUE E. TOMA. Can. J.

“…The intermolecular structure parameters are obtained from the crystal data [22] and fixed in the course of the calculations. The discrete molecular aggregates of DMSO so far proposed [6][7][8][9][10][11] are not seen in the solid-like structure. Some physicochemical properties of DMSO are shown in Table 2 together with those of N,N-dimethylformamide (DMF) for comparison [27,28].…”

“…Liquid DMSO is found to be associated according to cryoscopic [1], spectroscopic [2], relaxa tion [3], viscosity [4] and neutron inelastic scattering [5] measurements. From recent Raman and infrared spectroscopic data, the existence in pure DMSO of cyclic and linear dimers including linear polymers is reported, although the assignment of the bands is still in controversy [6][7][8][9], The result of an NMR measurement suggested the formation of cyclic dimers of 2-thiaindan 2-oxide in CDC13 [10]. Lumbroso et al measured the dipole moment of DMSO in cyclohexane and explained their result in terms of a mixture of linear dimers and cyclic chain aggregates [11], Although some X-ray diffraction investigations on the structure of solvated metal ions in DMSO have been carried out [12][13][14][15][16], an analysis of the liquid structure of pure DMSO has not been re ported.…”

The liquid structure of dim ethyl sulfoxide (DMSO) was investigated by X-ray diffraction. The intramolecular structure parameters were obtained as follows: S = 0 150(1) pm, C -S 180(1) pm, nonbonding C -0 267(4) pm and C ---C 271 (7) pm. It is suggested that the molecular arrange ment in the liquid state is sim ilar to that in the solid state. It is pointed out that not only the value but also the position of the dipole mom ent vector in the molecule is essential for dipoledipole interm olecular interactions and that the latter factor results in a higher melting point of DMSO than o f N ,N -dim ethylform am ide in spite of their sim ilar dipole moments.
