Abstract:In this paper, through using hydrothermal technique we utilized tris (hydroxymethyl )aminometh-ane ( Tris) as organic ligands and synthesized two Lindqvist -type [ V6 O19 ]5-based compounds [ Co ( Tris)3 (H2 O)3 ( H3 V6 O19 )]· H2 O (1) and [ Zn ( Tris)3 ( H2 O)3 ( H3 V6 O19 )]· H2 O (2).Their crystal structures have been determined by single -crystal X-ray diffraction analysis.Compounds 1 and 2 are isostructural, con-taining a mix-capped Lindqvist -type [ V6 O19 ]5-anion.One octahedron coordinative Co/Zn atom links with three bridging O atoms of anion , forming the"inorganic cap".Furthermore, three Tris organic ligands offer their nine O atoms to build [V6 O19 ]5-anion.Namely, between the 19 O atoms in [V6 O19 ]5 -, 9 O atoms come from three Tris ligands.These three Tris molecules become the "organic cap"of the anion, realizing the organic func-tionalization of [V6 O19 ]5-.Additionally, we also studied the electrochemical , and photocatalytic properties of the title compounds.
