Structural Characterization of a Series of N5-Ligated Mn^IV -Oxo Species.

ABSTRACT: Analysis of extended X-ray absorption fine structure (EXAFS) data for the Mn^IV -oxo complexes [Mn^IV (O)(^DMM N4py)]²⁺ , [Mn^IV (O)(2pyN2B)]²⁺ , and [Mn^IV (O)(2pyN2Q)]²⁺ (^DMM N4py=N,N-bis(4-methoxy-3,5-dimethyl-2-pyridylmethyl)-N-bis(2-pyridyl)methylamine; 2pyN2B=(N-bis(1-methyl-2-benzimidazolyl)methyl-N-(bis-2-pyridylmethyl)amine, and 2pyN2Q=N,N-bis(2-pyridyl)-N,N-bis(2-quinolylmethyl)methanamine) afforded Mn=O and Mn-N bond lengths. The Mn=O distances for [Mn^IV (O)(^DMM N4py)]²⁺ and [Mn^IV (O)(2pyN2B)]²⁺ are 1.72 and 1.70 Å, respectively. In contrast, the Mn=O distance for [Mn^IV (O)(2pyN2Q)]²⁺ was significantly longer (
