Sažetak
The shape of the coordination polyhedron in seven distorted structures of copper(II) chelates with naturally occurring amino acids and their N-alkylated derivatives was analysed by means of two methods: (1) the coordination polyhedron was described as a vector sum of all (four) bond vectors within the framework of spherical coordinates ; (2) the coordination polyhedron was presented within the framework of angles around copper. Copper coordination can be described as being square planar with tetrahedral/pyramidal distortion. A comparison of the crystal and theoretical (molecular mechanics) structures revealed that the best agreement was obtained with the molecular mechanics model based on coulombic interactions in the first coordination sphere.
