The title compound, C(14)H(12)N(2)O(4), shows an E conformation about the diazenyl N atoms. The crystal structure features layers of molecules with the primary connection between the layers afforded by carboxylic acid dimer motifs; no evidence for extensive pi-pi stacking between the layers was found.

Three new triorganotin(IV) complexes, the trimethyl, tributyl and tpphenyl privatives of 5-(4chlorophenylazo)salicylic acid, have been synthesised and characterised by H, C, Sn NMR, IR and elemental analysis and the crystal structure of triphenyltin-5-(4-chlorophenylazo)salicylate is reported o . The crystals are monoclinic, snace group P2]/n with a = 9.566(1) Ä, b = 14.550(2)Ä, c = 22.528(3)Ä, ß= 94.04(1), V= 3127.8(7) A , Ζ = 4 and D ca l c = 1.42 Mg.mThere is an encapsulated molecule of hexane incorporated in the structure. This complex adopts a monomeric distorted tetrahedral configuration with the ligand coordinated via a carboxylate oxygen. EXPERIMENTAL Chemicalsand reagents Me3SnCl (Merck), (Bu3Sn)20 (Merck) and (Ph3Sn)2Ü (Fluka AG) were used without further purification. Solvents used for synthesis were dried according to standard procedures. Preparation of 5-(4-chlorophenylazo)salicylic acid (LHH') p-Chloroaniline (5.0 g, 39.1 mmol) in a mixture of concentrated HCl solution ( 9 cm 3 ) and water (15 cm 3 ) was diazotised with cold aqueous NaNC>2 solution (2.70 g, 12 cm 3 ). The cold diazonium salt solution was added slowly to salicylic acid (5.40 g, 39.1 mmol), previously dissolved in 10% NaOH solution (31 cm 3 ) and held at 0-5° C in an ice-bath, with vigorous stirring. A yellow colour developed almost immediately and stirring was continued for 1 h. The reaction mixture was kept overnight at 4°C, followed by 3 h at room temperature and then acidified with acetic acid. The yellow precipitate was filtered, washed with water and dried in vacuo. The crude product was washed thoroughly with hexane, to remove tar-like material and then dissolved in methanol. Several recrystallizations from methanol gave the product in 62% yield; m.p. 252 -413 Brought to you by |

This work aims to fathom how the traditional and the indigenous product base of India will change if it rides the supersonic flight of the booming e-commerce sector. E-commerce has registered unprecedented growth in the developed world, and in the developing world, the transition is more visible and is garnering a foothold in a multitude of ways. Propelled by rising smartphone penetration, 4G networks, and increasing consumer wealth, the Indian e-commerce market is expected to grow significantly. Addendum to this will be the initiatives taken to indicate the transition. One such prospective sector that will ensure this is India's traditionally produced/manufactured or exclusive homegrown products. Linking these locally vibrant products or goods in states per se with e-commerce will ensure the growth and development of the said products and will stretch their outreach both in the country and worldwide. This in turn will ensure the development of the particular regions and the country as a whole apart from carving an undaunted place in the export portfolio of the country.
