The molecular structure of bis[1-(4-(trifluoromethyl)phenyl)-3-methyl-4-benzoylpyrazolon-5-ato]dimethyltin(IV) determined by X-ray diffraction methods shows an octahedral configuration with the metal on an inversion center. In this anomalous anti configuration equal Sn−O and C−O bond lengths in each ligand indicate a symmetrical O,O‘ bidentate form. In addition to this octahedral species, 119Sn NMR in CDCl3 shows a 5-coordinate complex, probably due to the loss of a Sn−O(acyl) bond.
