Sažetak
The interdependence between the side of apical coordination of H2O and steric crowding at the apical positions was investigated on a set of 34 copper(II) bis-complexes with N- and N, N- substituted amino acids. As a measure of steric crowding, overlapping volumes V* were used, calculated using a modified overlapping spheres (OS) method. Steric crowding around the apically bonded ligand was the same for this set of complexes as for the copper(II) bis-complexes with naturally occurring amino acids, with the optimal occupied volume values between 1 and 1.5 Å3. We also studied the interdependence between the length of the apical bond and distortion of the coordination polyhedron. The apical bond length showed sigmoidal dependence on the magnitude of distortion.
