Vibrational spectra of icosabedral closoborate anions B12X2−12 (X = H, D, Cl, Br, I)

On the rehydrogenation of decomposed Ca(BH4)2

“…The broad features contain contributions from several more narrow bands. A band at $2480 cm À1 , clearly observed in S3 and possibly present as a shoulder in S1 and S2, could stem from CaB 12 H 12 which is reported to have its strongest band at this position [26]. The origin of the remaining bands observed below 2600 cm À1 is not known.…”

Alkali and alkaline-earth metal dodecahydro-closo-dodecaborates: Probing structural variations via neutron vibrational spectroscopy

“…The vibrational spectra of dodecahydro-closo-dodecaborates in the solid state differ considerably from that of the isolated dianion, even in solution [11]. Allis and Hudson [12] reported that the solidstate vibrational spectrum of Cs 2 B 12 H 12 could not be reproduced with an isolated-ion calculation, but found good agreement using a solid-state calculation.…”

N‐Alkylation of Ammonioundecahydro‐closo‐dodecaborate(1–) for the Preparation of Anions for Ionic Liquids

“…2-, [20] and is also borne out by the ease with which H-D exchange can be achieved with DCl. [21] The melting points of the compounds (Table 1) are highest when tetramethylammonium serves as the counterion. It should be mentioned that the exact determination of the melting points by direct observation was sometimes not easy, as some of the melts are highly viscous liquids.…”
