Notizen:
A series of organotin(IV) maltol complexes R4 - xSnLx (1-4, 6; x = 1-3) and the dichloro-compound Cl2SnL2 (5) have been prepared and characterized on the basis of their IR-, 1H-, 13C- and 119Sn-NMR data. While an X-ray crystal structure analysis of Ph2SnL2 (4) and Cl2SnL2 (5) reveals distorted cis-octahedral structures, the Me2SnL2 molecule (2) adopts a skew-trapezoidal bipyramidal configuration with a very significant difference in the Sn-O(keto) bond distances. The tris-maltol complex BuSnL3 (6) exhibits a distorted pentagonal-bipyramidal geometry with the butyl carbon and a hy-droxy oxygen constituting the axial orientations.
