✦ Synopsis

During the course of mass spectral studies on the stability of bimetallic systems, an exceptionally abundant and stable Na6Pb cluster was discovered. For given experimental conditions, an intense molecular beam consisting exclusively of the particle Na6Pb is generated via self-assembly from a mixed vapor of sodium and lead. While this observation is reminiscent of the discovery of C60 or TlsC12, Na6Pb represents the first example of a binary finite-size 'alloy' (= 0.5 nm diameter) exhibiting such extraordinary stability.

Density functional studies of the abundant cluster Na6Pb and of its analogue Na6Mg are reported. The structure of Na6Pb has been optimized for a series of symmetry constraints (O h, D3d, D3h, C5v, C3v and C2v). The resulting binding energies fall within a narrow range of less than 0.1 eV whereas a s
