Abstract
The equilibrium constant for chelation of carboxylates to cis-diaqua t etraamine Co(III) complexes is highly sensitive to the tetraamine liga nd structure, basicity of the chelating carboxylate, and solvent polar ity. cis-Diaqua tetraamine Co(III) complexes that easily accommodate c helation of carboxylates are also highly reactive for hydrolyzing carb oxyl esters, amides, nitriles, and phosphate esters. The X-ray crystal strcuture of [(trpn)Co(eta(2)-O2CC(CH3)(3)]-(ClO4)(2) has been determ ined: trpn = tris(3-aminopropyl)amine, C14H33N4O10Cl2CO, orthorhombic, P2(1)2(1)2(1), a = 8.7822(3)Angstrom, b = 14.9959(6)Angstrom, c = 17. 5277(5)Angstrom, V = 2308.35(14) Angstrom(3), Z = 4.
