Abstract: Abstract: Pyridine and imidazole are connected by an azo group (h name="dbnd" />Nhesize 2-[(3′-pyridyl)azo]imidazole (3′-PyaiH) and this has been confirmed by X-ray structure determination. The N(1)-alkylation gives 1-alkyl-2-[(3′-pyridyl)azo]imidazole (3′-PyaiR′) (R′=Me (2a), Et (2b), Bz (2c)). The reaction between Mn(ClO4)2 ·6H2O and 3′-PyaiR′ in methanol has synthesized [Mn(3′-PyaiR′)4](ClO4)2 (3). The structure has been confirmed by single crystal X-ray diffraction study in one case, in addition to other spectral characterization. The structure reveals a tetrahedral orientation of four ligands coordinating through imidazole-N only. Cyclic voltammetry exhibits a Mn(III)/Mn(II) couple at >1.1V along with azo reductions. However, the reaction of MnCl2 ·4H2O+3′-PyaiR′ in the presence of NaN3 or NH4CNS (1:2:2 mole proportion) has synthesized Mn(3′-PyaiR′)2(X)2 (X=N3 (4), NCS (5)). [Copyright &y& Elsevier]
