The compound (1) has been prepared by reaction of with (1/1) and of with (1/1).Similarly, (2) (AzMe = 5-Me-2-(N=NC6H4Me-4)C6H3) has been obtained by reaction of with (1/1).Metathetical reactions between 2 and KX (1/1) have been shown to give (X = Br (3), I (4), CH (5)>.Compound 2 does not react with NaF but the corresponding fluoro complex (6) can be made by treating NaF with the complex obtained from the reaction of complex 2 with AgClO4.In the crystal compound 1 shows a distorted trigonal bipyramidal coordination around the tin atom.The equatorial positions are occupied by the three carbon atoms of the aryl ligands, with the tin atom lying 0.26 Angstroem out the equatorial plane on the side of the axial chloro atom.The 2-(phenylazo)phenyl ligand forms a five-membered chelate ring with a bite angle C-Sn-N of 70.3(1) deg.
