Complex formation with chelating ligands like 5-phenylazo-8-quinolinol, 5-(2I-carboxyphenylazo)-8-quinolinol, 1,2-dihydroxyanthraquinone (i.e., alizarin), and 1-nitroso-2-naphthol is due to nucleophilic attack on tin of the β-alkoxycarbonylalkyltin chlorides (a unique class of PVC stabilizer intermediates) with the subsequent elimination of hydrogen chloride. A number of complexes of the types R2SnL2, RSnL2Cl, R2SnLCl, R2Sn(LIHI)2, R2SnLII, and RSnLIICl (where R = CH3OCOCH2CH2—, C4H9OCOCH2CH2—, and CH3OCOCH(CH3)CH2—; LH = 5-phenylazo-8-quinolinol, 1-nitroso-2-naphthol; LIHHI = 5-(21-carboxyphenylazo)-8-quinolinol; and LIIH2 = 1,2-dihydroxyanthraquinone) and a thiocyanate derivative viz. (CH3OCOCH2CH2)2Sn(SCN)2 have been prepared. 5-Arylazo-8-quinolinols exhibit azo–hydrazone tautomeric equilibria but their complexes exist only in the azo form. β-Alkoxycarbonylethyltin alizarinates are somewhat different from other complexes. In these complexes two hydroxyl groups of alizarin have been utilised in complex formation, moreover, one of the two carbonyl groups of alizarin also remains involved in coordination to tin. In (CH3OCOCH2CH2)2Sn(SCN)2, the thiocyanate group is possibly linked to tin atom through nitrogen. All the complexes and the thiocyanate derivative have been characterised by elemental analyses, electronic, ir, and 1H nmr spectra. Possible structural features of the compounds are discussed.

Structural Isomers

An attempt has been made to study complex formation between 1,3,5-trinitrobenzene (TNB) and olefins by a gas chromatographic technique. A particular interpretation of the data indicates that the TNB – olefin complexes exhibit progressive increases in stability with increasing double-bond substitution. Steric effects are less pronounced than for olefin complexes with silver nitrate or molecular iodine. Olefins are well separated by carbon number, and differences in retention times among the structural isomers of each molecular weight are sufficiently characteristic to provide a basis for assigning major structural features.

AbstractTwo metal-organic coordination polymers constructed from tris(p-carboxylphenyl)phosphine oxide (TPOH3), namely, [Zn(TPOH)(2,2′-bipy)(H2O)·H2O·DMF]n (1) and [Zn2(TPOH)2(1,4-bix)2·5H2O]n (2) (2,2′-bipy=2,2′-bipydine, 1,4-bix=1,4-bis(imidazol-1-ylmethyl)benzene), were synthesized and identified by IR, elemental analysis and single-crystal X-ray diffraction analysis. Both of the 2,2′-bipy and 1,4-bix ligands tailor the complexes 1 and 2 into chain structures. The thermal behavior and solid state photoluminescence properties correlated with the corresponding structural features were investigated.
