A cyclopalladated phosphine selenide with an anionic acylselenourea ligand

The chloro-bridged cyclometallated palladium(II) complex [PdCl(kappa C,Se-C6H4P(Se)Ph-2)](2) reacts with 4-MeC6H4C(O)NHC(Se)NEt2 in the presence of base to give [Pd{kappa C,Se-C6H4P(Se)Ph-2}{kappa O,Se-4-MeC6H4C(O)NC(Se)NEt2}] in high yield. The complex was fully characterised by spectroscopic methods and also X-ray diffraction. This compound represents one of the few examples of a metal complex containing two different selenium-containing ligands. (C) 2016 Elsevier B.V. All rights reserved.
