This Diploma thesis consists of two parts: the research part and the methodological part. The reactions of halogenated N‒arylalkyliminodiacetamides XC6H2CH2N(CH2CONH2)2, (X = F, Cl, Br) I-V with copper(II) salts in aqueous solutions were investigated as well as the influence of the noncoordinating substituent of the ligands on the coordinating properties of ligands and their complexes. Five new complexes namely, [Cu(o-ClC6H4CH2N(CH2CONH2)2)2](NO3)2·H2O (1), [Cu(m-ClC6H4CH2N(CH2CONH2)2)2](NO3)2 (2) [Cu(p-ClC6H4CH2N(CH2CONH2)2)2](NO3)2·2H2O (3), [Cu(p- FC6H4CH2N(CH2CONH2)2)2](NO3)2·2H2O (4), [Cu(p-BrC6H4CH2N(CH2CONH2)2)2](NO3)2·2H2O (5), were prepared and characterized by infrared spectroscopy and thermal analysis. Crystal structure of [Cu(m-ClC6H4CH2N(CH2CONH2)2)2](NO3)2 (2) complex was determined by singlecrystal X-ray structural analysis. Coordination around the copper(II) ion can be described as a distorted octahedron. Molecules of complex (2) are trans-isomers with two O,N,O'-tridentate iminodiacetamide ligands that forms facconformation around the metal center. Conclusion based on data collected from infrared spectroscopy and thermal analysis is that remaining complexes 1,3,4,5 have molecular structure that is similar to molecular structure of complex 2. The methodological part of the Thesis includes descriptions of: the phenomenon of Liesegang rings in the context of educational outcomes appropriate to students of the second grade of high school; the role of achievement during planning, implementation and evaluation of project teaching. Appropriate methods and conditions of the experiment to create Liesegang rings are suggested. A methodological and didactic guide to the implementation of project teaching on the subject of Liesegang rings was developed.
