Aggregated manganese complex-nanolayered manganese oxide: a new hybrid molecular-inorganic material.

ABSTRACT

Layered materials such as clays, layered double hydroxides, and layered hydroxides are promising compounds for material science applications because, in addition to their structural and functional properties, the aggregation of these compounds with others results in new structural and functional characteristics. Notably, the aggregation of a metal complex and nanolayered material leads to new structures and properties. Mn oxides and complexes are different compounds, which show promising properties. Herein, a new hybrid molecular-inorganic material was synthesized by the aggregation of a manganese complex with a 2,4,6-tris(2-pyridyl)-1,3,5-triazine ligand and monolayers of Mn oxide. This new hybrid molecular-inorganic material was characterized by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy, Raman spectroscopy, thermogravimetric analysis, microanalysis, UV-Vis spectroscopy, nitrogen adsorption-desorption isotherm, magnetic properties, and electron paramagnetic resonance spectroscopy. All these methods showed that the aggregation of the manganese complex and layered Mn oxide occurred. A larger extent of aggregation for this hybrid molecular-inorganic material was observed compared to monolayered Mn oxide. The new material constitutes a new family of hybrid molecular-inorganic materials, in which transition metal complexes could be placed in a new environment.
