A Dimeric Mn(III) Complex of a Quadridentate Schiff Base Ligand.

Two crystallographically independent silver cations are present in the structure, Ag(2) located slightly above the center of a square of four oxygen atoms and Ag(1) in a

In particular, in complex 1·3CH 3 CN the Mn–Mn separation is reduced by the contraction of some of the Mn–O bond lengths, whilst in 2 · 2CH 3 CN · 1H 2 O the Mn–O–Mn

Ab- sence of these bands in the spectrum of the complex, and a 46 cm −1 red shift of the azomethine (-C=N-) band of the hydrazone Schiff base, indicate coordina- tion of H 2 L

Extended H¨uckel molecular orbital (EHMO) calculations have been performed in order to gain insight into the molecu- lar orbitals that participate in the super-exchange pathway by

Key words: Manganese, Phenanthroline Complex, π – π Stacking Interactions,

The crystal structure consists of ordered dinuclear units with Cu II and Mn II ions bridged by two oxygen atoms of the Schiff base ligand.. The coordination around the Mn II ion is
