First structurally characterized complex of an acyclic telluratedSchiff base[4-meOC_6H_4TeCH_2CH_2N=C(CH_3)C_6H_4-2-OH(L~1H)]having metal-tellurum bond;synthesis and crystal structure of [PdCl(L~1)]

摘要

Acyclicj telluratedSchiff base [4-MeOC_6H_4TeCH_2CH_2N=C(CH_3)C_6H_4-2-OH(L~1H)]has been synthesized by reacting 2-(4-methoxyphenyltelluro)ethylamine with omicron-hydroxyacetophenone.The L~1H on reaction with Na_2PdCl_4 forms a complex[PdCl(L~1)]in which the tellurated Schiff base coordinates in a tridentate mode.The proton and carbon-13NMR spectra of L~1H and the complex are characteristic.The single crystal structure of the complex is solved.The Pd-Te,Pd-Cl,Pd-O and Pd-N bond distances re 2.504(1),2.290(4),2.03 and 2.01(1)A,respectively.
