Abstract

The co-ordination chemistry of a tristhiourea tris(2-pyridylmethyl)amine ligand (L1) with a series of transition metal ions has been investigated. Crystallographic data show that large metal ions, with no geometrical preferences , such as Mn(II) and Cd(II), will form seven co-ordinate monocapped octahedral complexes, while smaller metal ions such as Zn(II) favour five co-ordinate trigonal bipyramidal structures. In a similar manner to the related bisthiourea complexes, the Ni(II) complex shows a strong preference for octahedral geometries resulting in the ligand binding asymmetrically. Spectroscopic (IR and NMR), spectrometric (MS) as well as electrochemical data for these complexes are reported.
