Chiral Distortion of Di(μ-sulfido)bis[oxomolybdenum(V)] Complexes of a Hexadentate Ligand N,N,N′,N′-Tetrakis(2-pyridylmethyl)-R-propylenediamine and Its Analogs

Abstract

Chiral distortion of the basal four pyridyl nitrogen donors of the titled complex [Mo2(O)2(μ-S)2{μ-N,N,N′,N′-tetrakis(2-pyridylmethyl)-R-propylenediamine}]2+ has been found to be the reverse to that of the corresponding di-μ-oxo complex, on the basis of the inverse pattern of the circular dichroism spectra. Asymmetric distortion of the dimolybdenum(III) dimer [Mo2(μ-OH)2(μ-CH3COO){μ-N,N,N′,N′-tetrakis(2-pyridylmethyl)ethylenediamine}]3+ has also been discussed.
