Abstract

Manganese(II), copper(II) and cadmium(II) complexes of p-coumaric acid (p-hydroxycinnamic acid) were synthesized. Their composition was established by means of elementary and thermogravimetric analysis. To study the molecular structure of synthesized compounds many miscellaneous analytical methods, which complement one another, were used: infrared (FT-IR), Raman (FT-Raman) and nuclear magnetic resonance ((1)H, (13)C NMR). The spectroscopic studies lead to conclusions concerning the distribution of the electronic charge in complexes in comparison with p-coumaric acid molecule and the type of metal ion coordination.
