The infrared spectra of dialkyltin dialkoxides

Preparation and Properties of Semiconducting Polycrystalline Tin Oxide

“…Since this absorption was not affected by the heat-treatment of the sample nor by the presence or absence of antimony, it is not connected with the band observed by Miloslavskii (8) centered at 16.4~ and shown to be due to excitation of impurity centers. Sn-O vibrations are known in this region, for instance in tin alkoxides (22) and have been reported (23) Conductance.--D-C conductances were found of samples which had been powdered in an agate ball mill and enclosed under pressure between steel electrodes in an insulating former for the purpose of the measurement. The apparatus for this measurement will be described elsewhere (25).…”

Coordination and catalysis of Zn2+ in epoxy-based vitrimers

“…From EXAFS measurements, we established that the coordination number of Zn 2+ in the epoxy-acid vitrimer system is very close to 4. The positive band centered at 1026 cm −1 , observed in the IR difference spectrum, is characteristic of the vibration ν C-O-M from a metallic alkoxide, [44][45][46] represented as a type III complex in Fig. 6.…”

“…The positive band centered at 1026cm -1 , observed in the IR difference spectrum, is characteristic of the vibration υC-O-M from a metallic alkoxide. [44][45][46] , represented as type III complex in figure 6. This confirms the presence of Zn-binded alkoxide groups, already inferred from the reaction sequence exposed scheme 2-C.…”

Organomercury alkoxides. Vibrational spectra and structure of MeHgOPh and PhHgOR (R = Ph, Me, Et)

“…organomercury compounds, including analogous thiolates, together with reported spectra and as signments for ROH [19,20], (MeO)z [21], (MeS)2 [22], (EtS)z [22], EtzO [23], H 3GeOMe [24], Et 2Sn(OMe)z [25], and PhB(OMe)z [26]. As found for PhHgOPh the frequencies of PhHg" modes are close to those reported by BARRACLOUGH et al [14] and GOGGIN and McEWAN [15], and relative intensities follow similar trends.…”
