 note = {An all-inorganic complex, [Mn2{(CVO3) 5}2]6- (1), was synthesized, and the structure determination reveals a dinuclear manganese complex coordinated by two cyclic pentavanadate ligands. The cyclic pentavanadate units sandwich the edge-sharing octahedral dimanganese core through, coordination of the oxido group of the pentavanadate. A. dinuclear cobalt complex with, a cyclic decavanadate, [Co 2(OH2)2(VO3)10]6- (2), was also synthesized. The structure analysis reveals a dinuclear cobalt complex with a macrocyclic decavanadate, which is composed of 10 VO4 units joined by the vertex. Sharings. The CoO6 octahedrons are edge-shared, with each cobalt octahedron coordinated to five oxido groups from the decavanadate. The remaining site is occupied by - water. The coordinated water molecules are supported with hydrogen bonds in two directions. Complex 2 in acetonitrile shows no reactivity with dioxygen even at low temperature, and the cyclic voltammogram of 2 shows no redox chemistry in acetonitrile. Complex 2 exhibits chromism by water exposure both, in the solid state and. in acetonitrile. Complex 2 is green-yellow in color, and. the addition of water causes the complex to turn brown. After heating the sample, it returns to its original color in a reversible manner. The EXAFS data in acetonitrile is also reported, and is consistent with the solid-state structure. © Wiley-VCH Verlag GmbH & Co. KGaA., 金沢大学理工研究域物質化学系},
