Back from #ICCOC-GTL18 in Oldenburg with lots of new ideas and plenty of great discussions! 🧪💬 I had the opportunity to share our work on low-valent group 14 chemistry and really appreciate the nice feedback and conversations. Always great to catch up with old friends and meet new ones!
A special milestone - my first paper as corresponding author out now in Organometallics @pubs.acs.org! 🎉 We've added group 16 to our usual group 14/15 playground. Our new chalcogenophosphinites show systematic spectroscopic, electronic and structural trends across the series.
Chalcogenophosphinites with a Cyclic Oligosilane Backbone
Abstract. A structurally authenticated series of chalcogenophosphinites, R2P(ChPh) (Ch = S, Se, Te), supported by a compact tetrasilaphosphacyclopentane ba

What a great week at the ICCC in Odense! It was great meeting everyone, learning about the great chemistry being carried out all around the world ^^ A special thanks goes to the organizing comittee for hosting such a great conference! @iccchemistry.bsky.social
What a great week at this years @iccchemistry.bsky.social in Denmark! Lots of amazing science and great people - an absolute blast. 🇩🇰🙌🏼 Special thanks to the organizing team and @lisakreimer.bsky.social, @lapluhp.bsky.social and @mrenrisoto.bsky.social for making it particularly fun! #ICCC46
Excited to finally see these beauties published 🌟 Thanks to the whole team! Check out our recent article in Inorganic Chemistry @pubs.acs.org 👇🏼 pubs.acs.org/doi/10.1021/...
Metalloid Tin Clusters, SnntBum, with α-Sn-Like Structural Motifs
Metalloid tin clusters represent an intriguing class of compounds that bridge molecular chemistry and the solid state, yet access to diverse examples remains limited. Herein, we present a mild, modular hydrostannolysis-type strategy that enables the synthesis of tin-based clusters stabilized by fairly small tert-butyl substituents, thereby overcoming the ligand-imposed structural limitations of established methodologies. The approach gave access to a series of clusters of different core sizes, including Sn11tBu12, featuring a [1.1.1]propellane-type backbone, as well as larger Sn15tBu14 and Sn16tBu16 derivatives adopting α-Sn-like core motifs with chair arrangement reminiscent of the diamond-type structure. Experimental characterization (X-ray crystallography and 119Sn Mössbauer spectroscopy) and computational analyses (NBO and QTAIM) corroborate near-zero charges at the apical tin centers; the frontier orbitals show pronounced multicenter character across the tin framework, and several deeper-lying orbitals exhibit “superatom”-like character. Additionally, this synthetic protocol also afforded a unique, heterobimetallic Sn/Pb spiro compound, revealing the compatibility of the method with multiple group 14 elements.
