摘要

The reaction of the diethyltin(IV) cation with pyridoxine (PN, vitamin B-6) in 80:20 (v/v) ethanol-water mixtures containing NO3- and Cl-, NO3- and AcO- or Cl- and AcO- ions in various molar ratios was investigated. The compounds [SnEt2(PN-H)]Cl(1),[SnEt2(PN-H)](NO3) . 2H(2)O (2) and [SnEt2(PN-2H)] (3) were isolated. These compounds were characterized by IR, Raman and Mossbauer spectroscopy and EI and FAB mass spectrometry. The structure of compound 1, determined by X-ray diffraction, consists of dimeric [SnEt2(PN-H)](2)(2+) units (in which two bridging-chelating hydrogen pyridoxinate anions link Sn atoms with coordination number five) and hydrogen-bonded Cl- ions. The behaviour of these compounds in DMSO-d(6) and DMF-d(7) was studied by NMR spectroscopy. (C) 2000 Elsevier Science Ltd All rights reserved. [References: 38]
