First structurally characterized complex of an acyclic tellurated Schiff base [4-MeOC6H4TeCH2CH2NC(CH3)C6H4-2-OH (L1H)] having metal–tellurium bond; synthesis and crystal structure of [PdCl(L1)]

Acyclic tellurated Schiff base [4-MeOC6H4TeCH2CH2NC(CH3)C6H4-2-OH (L1H)] has been synthesized by reacting 2-(4-methoxyphenyltelluro)ethylamine with o-hydroxyacetophenone. The L1H on reaction with Na2PdCl4 forms a complex [PdCl(L1)] in which the tellurated Schiff base coordinates in a tridentate mode. The proton and carbon-13 NMR spectra of L1H 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 are 2.504(1), 2.290(4), 2.03(1) and 2.01(1) Å, respectively.
