A Thorough Characterization of the Tellurocyanate Anion [K@crypt-222][TeCN] was synthesized from KCN, Te, and crypt-222 in acetone. We discuss fundamental properties of [TeCN]−: Single crystal X-ray diffraction, nuclear magnetic resonance (13C, 15N, 125Te...

Excited to kick off this new account with great news: our latest work just appeared in Angewandte Chemie (onlinelibrary.wiley.com/doi/10.1002/...)! Huge thanks to our fantastic collaborators from the groups of Florian Weigend, Xulian Xie, and Xue-Bin Wang!

Looking forward to a my visit at Heidelberg University. But first some views from the Königsstuhl!

[B(O2C2(CF3)4)2]− ([FPB]−): Repurposing This Weakly Coordinating Anion for Solid-State Molecular Organometallic (SMOM) Chemistry The perfluoropinacol borate-based anion [B(O2C2(CF3)4)2]−, [FPB]–, is developed as a weakly coordinating anion for single-crystal to single-crystal organometallic solid/gas reactivity, resulting in the isolation and characterization (including periodic DFT and IGMH analysis) of the σ-alkane complex [Rh(Cy2PCH2CH2PCy2)(exo-η2η2-norbornane)][FPB]. The synthetically useful solvent-free Na+ salt, Na[FPB], and oxonium acid [H(OEt2)2][FPB] are also reported.

A new(ish) anion on the block for SMOM chemistry. Kris Altus’ latest on the organometallic chemistry of [B(O2C2(CF3)4)2]−. As well as showing this anion is a useful one in organometallic chemistry there is a cautionary note about the toxicity of a starting material.

π-Complexes of Main-group Metal cations: Exploration of Lewis acid reactivity A series of cationic nido-clusters [E(η4-IDP)]+/2+ was prepared from the imidazolium-substituted diphosphate-diide (IPr)2C2P2 (IDP), including [1]+ (E = Ga) and [2b,c]2+ (E = Sn, Pb). As analogues of ...

Now out as a preprint!
We demonstrate how we can use our biradicaloid ligand to stabilise a series of main-group cations and their application to prepare pi-complexes of diatomic [EX]+ cations, including [GeF]+ and [SnF]+ :)

Well the flowers are from the AC members, non of my business ;-) But again, have a good start!

Had my last day as a substitute professor in Magdeburg yesterday. The flowers on the desk are for incoming @bunzenlab.bsky.social (curtesy of the inorganic department) All the best for the start!

Flash Communication: Cyanophosphide Transfer Reactions Cyanophosphides of the general form [RPCN]− can be viewed as cyanide adducts of phosphinidenes and are phosphorus species in the (+1)-oxidation state. We have recently reported on the stable cyanophosphide [DippTerPCN]K (DippTer = 2,6-Dipp2C6H3, Dipp = 2,6-iPrC6H3) and now investigate its reactions with ECln (E = Ge, n = 2; E = P, As, n = 3) in either salt metathesis or base-assisted dehydrohalogenation reactions. In the case of GeCl2, salt metathesis with [DippTerPCN]K afforded the dimer of a chlorogermylene [DippTerP(CN)GeCl]2. When only 0.5 equiv of GeCl2 was used, the diphosphanylgermylene [DippTerP(CN)]2Ge was generated in solution. With ECl3 (E = P, As), facile cyanophosphide transfer was achieved from DippTerP(H)CN in NEt3-assisted dehydrohalogenation, giving diphosphanes or arsaphosphanes of the type DippTerP(CN)ECl2 (E = P, As), respectively.

Ayu is keeping it up! This piece is about ArPCN- transfer to give Germylenes and phosphapnictanes! Thanks @maltefischer.bsky.social and @fabiandankert.bsky.social for their help! Thanks Organomteallics for the smooth proceedings! #31p #phosphorus

This would not have been possible without the hard work from Ayu, with amazing support from Edgar! Fabian Dankert did magic with the SCXRD data, Jonas Surkau carried out the IR/RAMAN studies and Andrey chipped in some CV-tricks. Great team effort! Congrats to everyone! #31P #phosphorus #ProudPI

Ayu’s work on CN/NC-isomerism in Dioxophosphoranes is just out in Chem.Sci. Here we show that Cyanophosphides can be cleanly oxidized with O2, giving [ArPO2(CN)]-. Surprisingly both, cyanide and isocyanide form simultaneously! Super exited about this! @likat.bsky.social
