Abstract:

Three crystal architectures, including one organic compound of benzoyl peroxide(1) and two clusters of tri-iron(III) and bi-cupper(II) with benzoic ligands(2 and 3), were self-assembled by an in situ redox way of benzoyl peroxide oxidants reacting with Mo, Fe and Cu powders, respectively. X-ray crystallographic results show that both the asymmetry tri-iron(III) cluster and the benzoylperoxide crystal architecture(2 and 1) with complicated 3D networks were constructed by intermolecular hydrogen-bonding interactions. Contrarily, the symmetrical bi-copper(II) cluster crystal architecture(3), only with π-π stacking between paralleled phenyl groups and without any intermolecular hydrogen-bonding interactions, only presented an 1D zigzag chain along the a-axis.
