Abstract
1-(4-Methoxyphenyl-telluro)-2-[3-(6-methyl-2-pyridyl)propoxy]ethane (L1) 2-methyl-6-{3-[2-({2-[3-(6-methyl-2-pyridyl)propoxy]ethyl}-telluranyl)ethoxy]propyl}pyridine (L2) and their complexes [PdCl2(L1)]2 (1), [PtCl2(L1)]2 (2), [HgBr2(L1)] (3), [PdCl2 (L2)]2 (6), [PtCl2(L2)]2 (7) and [(PdCl2)3(L2)2] (8) have been synthesized and characterized by IR, 1H and 13C NMR spectra. 3 on crystallization from acetone:hexane (2:1) mixture gives MeOC6H4HgBr (4) and [RTe+-HgBr2]Brâ (RÂ =Â -CH2CH2OCH2CH2CH2-(2-(6-CH3-C5H3N))) (5).The crystal structures of 1, 2 and 4 are solved. The 1 and 2 are 20-membered metallomacrocycles and do not dissociate in solution. The crystals of 1 and 2 have chloroform and benzene, respectively, in the lattice whereas 4 is a linear ArHgBr type species. The Pd/Pt in 1 and 2 has square planar geometry. The Pd-Te and Pd-N bond lengths in 1 are 2.530 (1)/2.5313(9) and 2.097(4) and 2.101(4)Â Ã
, respectively.
