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⋯π inter-actions.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
