Si–Si bonding in an Unsupported N-heterocyclic Silylene Dimer Stabilised by an Iminophosphorane-based Scorpionate Ligand versus Head-to-tail Coordination in the Sn and Pb Tetrylenes (dataset)

The data support the associated journal publication including supplementary information of the article. Further information around the data can be found in the main manuscript and the supplementary information including references. DFT: Computational data (e.g. log-files, fchk-files, sumviz-files) are available. These can be opened with standard computational software such as Gaussian/GaussView or simple text readers such as editor or notepad; sumviz with AIMAll. The atomic coordinates are also available via the supporting information of the article. NMR: NMR data as spectrometer (Bruker) folders for individual experiments are provided. These can be opened with common NMR software such as MNova or NMRium.
