Extension of molecular mechanics to high-coordinate metal complexes. Calculation of the structures of aqua and nitrato complexes of lanthanide(III) metal ions
Abstract
Molecular mechanics methods have been used to calculate the diverse geometries found in 58 known structures of 8- to 12-coordinate aqua- and nitratolanthanide(III) complexes. A simple model based on the replacement of L-M-L bending interactions with nonbonded interactions between the ligand donor atoms and the use of harmonic M-L stretching potentials is shown to yield very reasonable geometric results. A method of structure specification for coordination compounds is presented that allows these calculations to be carried out by using the MM2 program without requiring any software modification. 52 refs., 9 figs., 7 tabs.
