“…The reaction of salicyclic acid and Sn(OMe) 2 is known to generate a product containing a related six-membered SnO 2 C 2 O heterocycle. 28 Thus, by analogy, Sn 2 (cit) 1 also contains one tin in this environment, while the second tin is bound to the two bidentate methylene carboxylate groups [ν asym (CO 2 Sn) 1553 (br) cm Ϫ1 ], presumably intermolecularly given the low solubility of the species. The two CH 2 CO 2 moieties appear non-equivalent in the 13 C cross polarisation magic angle spinning (CP MAS) NMR spectrum of 1 (δ 48.8, 52.9) though the two tin environments must, however, be very similar as they only give rise to line broadening in both the Mössbauer and 119 Sn NMR spectra, rather than resolvable signals for each metal environment.…”

The suggestion were confirmed by a band in electronic spectra which is assigned to ( 4 A 2 ------- 4 T 1 (P) ) transition (Honnick & Zuckerman 1978).

Some new metal(II) dichloride complexes with the ligands substituted nitrones of the general formula [ML 2 Cl 2 ], where M= Co(II), Ni(II), Cu(II), Zn(II) and Cd(II), L=OCH=CHCH=C-CH=N(O)C 6 H 4 X (X=H,p-CH 3 ,CH 3 O,CH 3 CO,F,Cl,and Br) have been prepared and characterized by elemental analysis, IR, 1 H, 13 C NMR and Vis/Uv spectroscopy. The IR spectral data showed that the nitrone ligands coordinated with the metal ion through the most active atom of the N-oxide to give square planner coordinate (Cu,Ni,) complexes and (Zn,Cd,Co) tetrahedral complexes. No correlation was observed between the N-O vibrations stretching high frequency ν (N-O) of the complexes and the Hammet (σ) constants.
