Abstract

The synthesis and characterization of the triethanolamine (TEA) complexes Sc(TEA)₂Cl₃ (1), Y(TEA)₂(ClO₄)₃·3C₅ H₅N (2), Fe(TEA)₂Cl₃ (3), Ni(TEA)₂Cl₂ (4), Zn(TEA)₂Br₂ (5), Zn(TEA)₂(NO₃)₂ (6), Cd(TEA)₂Cl₂ (7), Cd(TEA)₂(NO₃)₂ (8), Pb(TEA)₂(OAc)₂ (9) and Bi(TEA)₂Cl₃ (10) are reported. The structures of 2 and 8, determined by X-ray diffraction, unexpectedly revealed eight-coordinate metals in both cases. Both structures adopt a distorted hexagonal bipyramidal configuration in which the atoms in the hexagonal plane alternately fall above and below the plane. In 2, the tree pyridines as well as the three perchlorates are involved only in hydrogen bonding to the OH groups of different TEA ligands, causing a novel distortion of the coordination sphere. Compound 8 represents an unusual example of the relatively rare coordination number eight for cadmium(II).
