“…Weak molecular ions were detected for L2InCH3' and LzInC6Hst, and LInCH,' and LlnC6Hst ions are also present in low but significant abundance. The formation of such singly charged MX2+ ions is usual for indium(II1) compounds (16,17). The FD spectrum of L21nCl is quite different from those just discussed.…”

“…Raman spectra are consistent with tetrahedral geometry for this species.10" 13 Hanson and Plane14 provided evidence for the existence of InCl4" in water/methanol solutions, the Raman spectrum of which is different from the only species in aqueous solution which may have the 1:4 ratio of In3+:C1". The principal feature in the Raman spectrum of aqueous indium chloride solutions is a somewhat asymmetrical, polarized band which shifts from about 311 to 279 cm"1 as the chloride-to-indium ratio is increased.…”

The chloro complexes of indium(III) generate closely spaced, polarized Raman lines (stretching vibrations of indium-chloride bonds) which are observed as a single, broad, band profile. The band maximum shifts from 311 to 279 cm"1 as the chloride-to-indium ratio is increased from 0.48 to 15.9. Several numerical procedures have been applied to the digitized band profiles in order to investigate their usefulness for extracting the hidden information concerning the number of lines and their parameters. These were asymmetry analysis, including finding the centroid, the lower and upper semi-half-band width and the third moments, factor analysis, numerical band fitting, and stability constant modeling. For the compositions studied evidence for four species is presented: [InCl(H20)5]2+, [InCl2(H20)4]+, [InCl3(H20)3], and [InCl4(H20)2]". All methods failed to give reproducible stability constants.Plane14 assigned the contour to InCl2+(aq), InCl2+(aq), and InCl4'(aq). Woodward and Taylor12 even suggested InCl52" and InClfi3" ions were being formed but knowledge of the

“…of which no examples are known in the solid state; InL,+ is an indium(II1) derivative, requiring no unpaired electrons, formally analogous to the InMe,+ cation (8,9), and isoelectronic with the neutral Cd[Co(CO),],. It is worth noting that InL,+ species are the most abundant ions of the electron ionization mass spectra of indium(l1I) halides (10,11).…”

Field ionisation/field desorption mass spectra are reported for Mn2(CO)10, Cd[Co(CO)4]2 and some adducts, In[Co(CO)4]3, bipy•Zn[Co(CO)4]2, and bipy•M[Mn(CO)5]2 (M = Zn, Cd). The spectra are extremely simple, and the small number of easily identified species includes the molecular ion in some cases. The relative abundance of the fragments is discussed in terms of known stabilising factors in such compounds. No spectra could be obtained from Co2(CO)8 or Fe2(CO)9, which may be the result of their carbonyl-bridged structures.

The use of Raman spectroscopy in the study of anion exchange of complex anions

Abstract: It is shown that Raman spectroscopy can be used to identify complex anions sorbed on an anion exchange resin. Results for [AuC14]-and [AuBr4]-, and for anionic halo-complexes of indium(III), are described.
