Abstract: Compounds  [(C₂H₅)₃NHl₂CuCl₄ (I), [(C₂H₅)₃NH]₂CuCl₃Br (II), [(C₂H₅)₃NH]₂CuCl₂Br₂ (III),  [(C₂H₅)₃NH]₂CuClBr₃ (IV), and [(C₂H₅)₃NH]₂CuBr₄ (V) were prepared by crystallization from ethanolic solutions. Changes in the composition of the complexes were accompanied by changes in the structure of the coordination polyhedron from a distorted tetrahedron of various degree of distortion up to a distorted octahedron. In consonance with this fact, the d—d transition energies as well as the values of the g factors correspond to a compressed tetrahedron in the case of compounds J, II, and III, and to an elongated octahedron in the case of compounds IV and V.
