Steric control over molecular structure and supramolecular association exerted by tin- and ligand-bound groups in diorganotin carboxylates. Organometallics 22 (22) : 4599-4603. ScholarBank@NUS Repository. https://doi.org/10.1021/om0340140 | Abstract: | Structural data (X-ray and solution and solid-state 119Sn NMR) show that skew-trapezoidal-bipyramidal diorganotin compounds of 2-quinaldate are invariably monomeric, owing to the steric bulk of the carboxylate ligand. In contrast, most of the analogous compounds of 2-picolinate (2-pic) can increase their coordination number by polymerization or the incorporation of solvent in their coordination sphere in the solid state. The exceptional compound is tBu2Sn(2-pic)2 (3), for which no increase in coordination number is apparent, a result that is correlated with the bulky tert-butyl groups. Thus, judicious choice of tin or ligand substituents can be exploited to dictate coordination number and/or the degree of supramolecular aggregation in the investigated systems. | Source Title: | Organometallics | URI: | http://scholarbank.nus.edu.sg/handle/10635/94885 | ISSN: | 02767333 | DOI: | 10.1021/om0340140 |
