Bis{2-[(E)-(5-tert-butyl-2-hy-droxy-phen-yl)diazen-yl]benzoato}dimethyl-tin(IV).

ABSTRACT: In the title diorganotin dicarboxyl-ate, [Sn(CH(3))(2)(C(17)H(17)N(2)O(3))(2)], the tin(IV) atom is six-coordinated by four O atoms derived from asymmetrically coordinating carboxyl-ate ligands, and two methyl-C atoms. The resulting C(2)O(4) donor set defines a skew-trapezoidal bipyramid with the Sn-C bonds disposed over the weaker Sn-O bonds. Within each carboxyl-ate ligand, the hydroxyl-H atom forms bifurcated O-H?(O,N) hydrogen bonds with carboxyl-ate-O and azo-N atoms. The dihedral angles between the benzene rings in the two ligands are 10.44?(11) and 34.24?(11)°. In the crystal, centrosymmetric dimers are formed through pairs of Sn?O inter-actions [2.8802?(16)?Å], and the dimers are linked into supra-molecular layers in the ac plane by C-H?? inter-actions.
