Abstract

Reactions of RSnCl3 (R = Et and nBu) with internally functionalized oximes in 1:1 and 1:2 stoichiometric ratios in anhydrous benzene afforded non-ionic fibrous complexes of the general formula RSnCl3 · nHONC(R?)Ar [R = Et and Bu; R? = H, Me n = 1 and 2 (1–8); R? = only Me (9–11); Ar = 2-NC5H4, 2-OC4H3. Except for 1:1 furyl derivative, the value of 119Sn chemical shifts for all these derivatives in the 119Sn NMR spectra suggests hexa-coordination around tin atom. The crystal and molecular structures of one of the adducts nBuSnCl3 · HONC(Me)Py-2 · C6H5Me (2.tol.) and of a trinuclear hydroxo bridged stannoxane {nBuSnCl2(ONC(Me)Py-2)OH}2SnnBuCl · 0.5 HONC(Me)Py-2 (12), obtained on hydrolysis of nBuSnCl3 · 2HONC(Me)Py-2 (6), revealed a distorted octahedral environment around tin with the participation of both nitrogen atoms (ring as well as oxime nitrogen atom of the same ligand moiety) in coordination. In compound (2.tol.), the existence of intramolecular hydrogen bonding between the hydroxyl proton of the ligand moiety and the chlorine atom stabilizes the geometry. Unique asymmetric Sn–O(H)–Sn and Sn–O–N–Sn bridges are present in compound (12), resulting in a linear trinuclear stannoxane framework.
