Transition metal complexes of tris(aminomethyl) phosphine oxide (tampo) - Thermodynamic and X-ray diffraction studies
Original language description
The coordination behaviour of tris(aminomethyl) phosphine oxide (tampo) to selected transition metal ions was studied. In the case of Co(III), Ni(II) and Cu(II) complexes with metal-to-ligand 1: 2 stoichiometry, bis(tripodal) tampo coordinations forming octahedral coordination spheres (in the case of Cu(II) complex with significant Jahn-Teller distortion) were found by X-ray diffraction analysis. Based on the potentiometric study, the tripodal coordination of the title ligand is also expected in solution. The stability of the metal complexes follows the Irving-Williams trend. Compared with the structurally "parent" 1,1,1-tris(aminomethyl) ethane (tame) ligand, the complexation of tampo occurs at a lower pH as the consequence of low ligand basicity [logK(1) = 6.72(1), logK(2) = 5.34(1) and logK(3) = 3.82(1)], although the values of the stability constants of the metal complexes are relatively low.
