method was employed to link Anderson‐type polyoxometalate (POM) clusters and transition‐metal clusters by using a designed rigid tris(alkoxo) ligand containing a pyridyl group to form a three‐fold interpenetrated anionic diamondoid structure and a 2D anionic layer, respectively. This technique facilitates the integration of the unique inherent properties of Anderson‐type POM clusters and cuprous iodide
Functional polyoxometalates from solvothermal reactions of VOSO<sub>4</sub> with tripodal alkoxides – a study on the reactivity of different “tris” derivatives
blocks for post-functionalisation. Therefore, solvothermal reactions of VOSO4 with various tris(hydroxymethyl)methane derivatives in alkaline methanolic solutions were investigated. In doing so, new POM fragments were isolated and characterised. The binding modes of the functionalised tripodal alkoxides turned out to be surprisingly different.

Abstract Polyoxovanadate-alkoxide (POV-alkoxide) clusters are promising charge-carrier candidates for non-aqueous redoxflowbatteries (NRFBs), due in part to their easily-modified bridging alkoxide ligands. Herein, we report a series of new POV-alkoxide clusters featuring polar functional groups bound to the tertiary carbon of a tripodal, tris(hydroxymethyl)methane ligand (TRISR; R = C2H5, NO2, NMe3+
Construction of Two High‐Nuclear 3d‐4d Heterometallic Cluster Organic Frameworks by Introducing a Bifunctional Tripodal Alcohol as a Structure‐Directing Agent
Two unique heterometallic clusterorganicframeworks, [Cd4MnIII4MnII6(Tri)4(CH3COO)14(μ4‐O)2(μ3‐O)2(H2O)2] Cd(H2O)2⋅9 H2O (1) and Cu[Cd5Cu6(Tri)4(CH3COO)9(H2O)4]2(CH3COO)3⋅24 H2O (2) (H3Tri=2‐(hydroxymethyl)‐2‐(pyridine‐4‐yl)‐1,3‐propanediol), have been successfully prepared by employing a bifunctional tripodal alcohol ligand as a structure‐directing agent. Crystal structure analyses reveal that 1
