摘要:
The reactions of the potent and widely used anti-inflammatory drug diclofenac, HL,with diorganotin(IV) oxides were studied. The dimeric tetraorganodistannoxane complexes [Me2LSnOSnLMe2](2), [Bu2LSnOSnLBu2](2), [Ph2LSnOSnLPh2](2) and the dibutyltin complex [Bu2SnL2], have been prepared and structurally characterized in the solid state by means of vibrational and Sn-119 Mossbauer spectroscopy. Determination of lattice dynamics by temperature-dependent Sn-119 Mossbauer spectroscopy. From the variable-temperature Mossbauer effect, the Debye temperature was determined. The complexes have been characterized in solution by NMR (H-1 and C-13) spectroscopy. Vibrational, Mossbauer, and NMR data are discussed in terms of the proposed structures. (C) 2003 Elsevier B.V.
