Abstract

Homoleptic germanium(II), tin(II), and lead(II) complexes of the general formula M(2-PyCHCOCF3)(2) (M = Ge, Sn, Pb; Py = pyridine) were synthesized by treating the corresponding silyl amides [M{N(SiMe3)(2)}(2)] with two equivalents of a 3,3,3-trifluoro-1-(2-pyridyl)prop-1-en-2-ol (2-PyCHCOHCF3) ligand. Single-crystal X-ray diffraction revealed the bidentate chelation of 2-PyCHCOHCF3, which imposes a distorted trigonal bipyramidal geometry for all three molecular structures; this distortion is highest for the lead compound, probably as a result of the high s character of the lone pair of electrons present on the metal centers. The monomeric nature of the compounds in solution was confirmed by multinuclear NMR spectroscopy, whereas a polymeric structure is observed for the lead complex in the solid state.
