title: Naked deltahedral silicon clusters in solution: synthesis and characterization of Si9(3-) and Si5(2-).
abstract: Elusive for over 100 years, deltahedral Zintl ions of silicon are finally synthesized and structurally characterized. The two clusters reported here, Si93- and Si52-, are analogous to known clusters of the heavier members of this group: Ge, Sn, and Pb.
