The geometric features and spectral characteristics of some pentaamineruthenium(II) complexes.
The geometric and bonding parameters of Ru(II) pentaaminepyridine and cyanopyridine complexes are examined via ab initio molecular orbital calculations. The results show that the nitrile bonded complexes are more stable than the pyridine bonded ones by 71-625 kJ mol(-1) depending on the position of the nitrile group. Solvent dependence of MLCT bands are interpreted and discussed.
