Abstract
Two isostructural mononuclear complexes with the formula [MIIIL(N3)(OH2)] × 1/2N2 (M = Mn for (1) and Fe for (2); H2L = N,N′-bis(3-ethoxysalicylidene)-1,2-propanediamine) have been synthesized and characterized by physico-chemical and spectroscopic methods. Each compound consists of a mononuclear complex molecule and half of a nitrogen molecule of crystallization. Each metal atom in the complexes has a slightly distorted octahedral geometry, coordinated by two nitrogen and two phenolic donors of L, the oxygen atom of the water molecule, and the nitrogen atom of the azide group. Determination by GC/MS analysis indicated that complex (1) has no catalytic property for the dioxygen oxidization of cyclohexene, but complex (2) has good properties.
