From August 4th –  August 11th silicon chemists from all over the world met at Shandong Univeristy in Ji´nan (China) for the 18th Symposium on Silicon Chemistry (ISOS), which was held in conjunction with the 6th Asian Silicon Symposium (ASIS). Besides a series of talks, the participating PhD…

Annually, the TUM graduate school awards this prize endowed with 1500,-€ and a medal to the three best Ph.D. graduates. Out of all “summa cum laude” graduates the jury selected those who have displayed the highest excellence in publications within a short or normal dissertation time. The medal was…

Silicon adapts in the predominant α modification the cubic diamond structure that significantly limits solar cells efficiency. A surprisingly simple way allows for rebuilding new three-dimensional structures of tetrel elements. For article see: L.-A. Jantke, A. J. Karttunen, T. F. Fässler …

Zwitterionic Molecules Comprising Zintl Clusters For the first time the introduction of phosphine moieties at tetrel Zintl clusters was achieved and a series of novel mixed-functionalized cluster compounds bearing phosphine substituents is presented. Besides providing a novel class of bulky…

π–complex or intermetalloid cluster? Zn atoms serve for both. Either covalent coupling of two Zn vertex atoms or Lewis-acid Lewis-base interactions leads to novel intermetalloid clusters with Zn. The reactions of Zn(I) compounds of the type Zn2L2 with solutions of the Zintl phase K4Ge9 in liquid…

The new Li-Si-P ternary phase compounds Li8SiP4 and Li2SiP2 are the starting point of a large compound class. Both compounds form structures based on SiP4 tetrahedral building blocks and reveal a significant lithium ion mobility. The compounds were characterized by XRD and solid-state NMR, and Li…

Nanostructured Group 14 semiconductors attract significant attention because of a broad range of potential applications. We describe a general and controllable fabrication method for Ge nanomorphologies with tunable composition using the controlled reaction of [Ge9]4− Zintl clusters to a solid…

[Ge2]4– Dumbbell with Very Short Ge-Ge Distances in the Zintl Phase Li3NaGe2 – A Solid State Equivalent to Molecular O2 L. M. Scherf, A. J. Karttunen, O. Pecher, P. C. M. M. Magusin, C. P. Grey, T. F. Fässler Angew. Chem. Int. Ed., 2015, 55, 1075–1079. DOI: 10.1002/anie.201508044  erscheint ein…
