Synthesis and multinuclear NMR studies of 3-aminopropyl(aryl)chalcogenides, NH2CH2CH2CH2EAr (E = Se, Te), and their complexes with Pt(II) and Pd(II)
摘要:
The asymmetric ligands, 3-aminopropyl(aryl)tellurides (1a, 1b) [Ar = Ph (a); C6H4-OMe (b)] and 3-aminopropyl(phenyl)selenide (2) and their complexes with platinum(II) and palladium(II), viz. [PtCl2(1a, 1b)] (3, 4), [PtCl2(2)] (5), [PdCl2(1a, 1b)] (6, 7), [PdCl2(2)] (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.
