Assciation and fragmentation of imidotin(II) complexes containing donor-funcationalised peripheries; towards new three-dimensional main group metal ligands

摘要

Structural studies of a series of tin(II) imido cubanes, [SnNR]_4, containing donor-functionalised organic substituents (R), have allowed the systematic investigation of the factors controlling and affecting association of these architypal tin(II) complexes in the solid state. In addition to steric shielding of the Sn_4N_4 cores, intra- and inter-molecular O and N donation modifies or curtails association via Sn…Sn interactions, and can even facilitate fragmentation of the cubane cores.
