The disproportionation reaction of the subvalent metastable halide SnCl proved to be a powerful synthetic method for the synthesis of metalloid cluster compounds of tin. Now we present the synthesis and structural characterization of the anionic metalloid cluster compound [Sn9[Si(SiMe 3)3]2]2-3 where the oxidation state of the tin atoms is zero. Quantum chemical calculations as well as Moessbauer spectroscopic investigations show that three different kinds of tin atoms are present within the cluster core. Compound 3 is highly reactive as shown by NMR investigations, thus being a good starting material for further ongoing research on the reactivity of such partly shielded metalloid cluster compounds.
Chemiluminescent reactions of ground and metastable states of the group IV a elements with halogens

Earlier work on chemiluminescent beam-gas reactions of the ground states (3Pj) of Si, Ge, and Sn with F2 and of both ground and metastable states (1D, 1S) of Sn with Cl 2, Br2, and I2 is extended to include reactions of both ground and metastable states of Si, Ge, and Sn with F2, Cl2, Br2, I2, and ICl. Chemiluminescent products of metal halides and/or dihalides were observed in all of these reactions, although attempts to observe that in the similar reactions of Pb were unsuccessful. In ICl reactions with Si, Ge, and Sn, both monochloride and dichloride emission occurs, confirming the previously proposed mechanism for creating dihalide emission in Sn reactions with Br2 and I2 via a monohalide intermediate.
