Advancement of the chemistry of organotin–Schiff base complexes: a crystallographic perspective
Rachana Joshi
Abstract
the powerful technique of X-ray crystallography, providing a robust foundation for understanding their three-dimensional architectures and bonding motifs. A central focus is directed towards the coordination versatility exhibited by Schiff bases derived from a diverse array of precursors, including amino acids, hydrazines, hydrazones, dihydrazones, and amino alcohols, which showcase their remarkable ability to engage with tin centres in multifaceted ways, supporting a spectrum of coordination geometries and oxidation states. Aliphatic and aromatic Schiff bases are explored extensively, revealing their propensity to form diverse additives and chelates with varying stoichiometries and coordination mechanisms, existing in both neutral and deprotonated forms.
