- In this paper a novel synthetic route, being a paradigm of the "direct synthesis" approach, is proposed for the preparation of heterometallic Mn/V compounds by a one-pot reaction. Two synthesized complexes, (NH4)(2)[Mn-2(HGly)(H2O)(10)][V10O28]center dot(HGlY)center dot 2H(2)O (1) and (NR4)(2)[Mn(beta-HAIa)(H2O)(5)](2)[V10O28]center dot 2H(2)O (2) (HGly = glycine, beta-HAla = beta-alanine) have been fully characterized by elemental analysis, single-crystal X-ray diffraction, cyclic voltammetry, magnetic susceptibility, FTIR and EPR spectroscopy. Thermal degradation of these compounds lead to the formation of porous, solid mixed oxides V2O5/MnV2O6 in a ratio of 3:2, which were analyzed by X-ray phase analysis and scanning electron microscopy with energy dispersive X-ray microanalysis (SEM/EDX). Additionally the ability of 1 and 2 to act as oxygen evolving water oxidation catalysts under visible light-driven conditions have been studied in a Clark type cell and by ex situ EPR spectroscopy.
