Complex compounds of Some p, d, and f metals with 2,4,6-Tris(N,N- dimethylaminomethyl)phenol (HL): Crystal and molecular structure of H 4L(NO3)3 · H2O and H 4LCl3 · 3H2O

Eight aluminum, cobalt(II), copper(II), cadmium, samarium(III), and europium(III) complexes with 2,4,6-tris(N,N-dimethylaminomethyl)phenol (HL) were isolated in the crystalline state and studied by physicochemical methods (IR and UV-Vis spectroscopy, potentiometry). The complexation processes of sin- gly, doubly, and triply charged metal ions with HL were studied by spectrophotometry and potentiometry, the composition of complexes was determined, and the stability constants were calculated. The crystal and molecular structures of 2,4,6-tris(N,N-dimethylaminomethyl)phenol trichloride and trinitrate H 4L(NO3)3 · H2O and H 4LCl3 · 3H2O were studied by X-ray diffraction. © Pleiades Publishing, Ltd., 2011.
