alkoxides ([(OR)Sn(NMe2)]n) and tin(II) alkoxides ([Sn(OR)2]n) were investigated as precursors for the production of tin oxide (SnOx) nanowires. The precursors were synthesized from the metathesis of tin dimethylamide ([Sn(NMe2)2]2) and a series of aryl alcohols H-OAr = H-OC6H4(R)-2: R = CH3 (H-oMP), CH(CH3)2 (H-oPP), C(CH3)3 (H-oBP)] or [H-OC6H3(R)2-2,6: R = CH3 (H-DMP), CH(CH3)2 (H-DIP), C(CH3)3 (H-DBP)]}

Monomeric 2-pyridylbis(trimethylsilyl)methyltin(II) compounds Sn(R)X [= (SiMe3)2C5H4N-2 and = (1), l (2), or (SiMe3)2(3)] were prepared from (LiR)2 and (a) SnCl2 or Sn(OC6H3But2-2,6)2(1), (b) 2SnCl2(2), or (c) Sn[N(SiMe3)2]2(3); their X-ray structures show that the ligands are invariably bonded to tin in a chelating fashion in the crystal with SnâC and SnâNC5H4 bond lengths of 2.35(2) and 2.42(2)(1), 2.32(2) and 2.27(3)(2), and 2.356(8) and 2.299(5)à (3), respectively, but in C6D5CD3 solution there appear to be (n.m.r.) C5H4NâSn dissociative processes (ÎGâ¡ca. 43 ± 2 kJ molâ1).

The title compound, [Sn(C14H21O)2] (I), contains a two-coordinate tin metal center with Sn-O distances of 2.003 (3) and 2.044 (3) angstrom, and an O-Sn-O angle of 88.8 (1)degrees.
), as well as some heteroleptic metallates, such as [Li(OEt2)2][Sn(n)BuHyp2] (3d), [Li(OEt2)2][Pb(n)BuHyp2] (4d), [Li(thf)4][PbPhHyp2] (3e), and [K(thf)7][PbHyp2N(SiMe3)2}] (3f), were synthesized and crystallographically characterized. Through oxidation by tin(II) and lead(II) bis(trimethylsilyl)amides or the related 2,6-di-tert-butylphenoxides, they had been oxidized to yield in most cases the corresponding
