Generation of Gas-Phase Ge, Sn, and Pb Cluster Anions from Various Sources and Comparison to Solid-State Analogues

The [Sn9Pt2(PPh3)]2- and [Sn9Ni2(CO)]3- Complexes: Two Markedly Different Sn9M2L Transition Metal Zintl Ion Clusters and Their Dynamic Behavior

“…Instead, the potassium-coordinated ion pair, K[Sn 9 Pt 2 (PPh 3 )] 1- , appears as the parent ion with a spectacular mass envelope arising from the multiple isotopes of Sn and Pt. Fassler et al found similar results with the naked group 14 cluster anions . The two other prominent ions are the oxidized molecular ion, [Sn 9 Pt 2 (PPh 3 )] 1- , and the ligand-free protonated binary ion, [HSn 9 Pt 2 ] 1- .…”

“…The electrospray mass spectrum (negative ion mode) recorded from a DMF solution of crystalline [K(2,2,2-crypt)] 2 [Sn 9 Pt 2 (PPh 3 )] is shown in Figure . As is common for these types of Zintl ions, ,− the [Sn 9 Pt 2 (PPh 3 )] 2- molecular ion is not observed.

Gas Phase, Solution, and Solid State Alkali Ion Binding by the [NbE8]3- (E = As, Sb) Complexes: Synthesis, Structure, and Spectroscopy

“…The protonated analogues of these ions are also present. Alkali ion extraction from 2,2,2-crypt in the gas phase has been observed in the mass spectral studies of other Zintl ion transition metal complexes as well as the naked Group 14 and 15 Zintl ions. ,

Anodic Electrodeposition of Germanium Films from Ethylenediamine Solutions of Deltahedral Ge[sub 9][sup 4−] Zintl Ions

“…25 They observed exactly the same cluster sizes and the same traces of germanium oxides. The presence of oxides, in our case, is most likely due to oxidation of small amounts of negatively charged germanium species in the form of clusters or in intermetallics counterbalanced by potassium cations, i.e., K x Ge y , on the surface of the films.…”
