The asymmetric ligands, 3-aminopropyl(aryl)tellurides (1a, 1b) and 3-aminopropyl(phenyl)selenide (2) and their complexes with platinum(II) and palladium(II), viz. (3, 4), (5), (6, 7), (8), <(Me)ClPd(1b)> (9) and <(Me)ClPd(1b)2> (10) have been made and characterized.Complexes 3-8, have square planar geometry around the metal (Pd or Pt) with the (Te,N)- or (Se,N)-ligand coordinated in a bidentate mode and the two chlorines cis to each other.Complex 9 also has a square planar geometry, with Me trans to nitrogen and Cl trans to tellurium.In complex 10 where Pd appears to be in a square planar geometry the two tellurium atoms are judged to be trans to each other.Keywords: Alkyl; Amine; Aryl; Group 16; Group 10; Chalcogenide
