A novel U(VI)-substituted tellurotungstate, Na13H6[{NaWU3O10(H2O)3}(B-α-TeW9O33)3]·55H2O (U3TeW), was successfully synthesized through the reaction of trivacant Keggin precursors with 5f U(VI) ions. The compound was systematically characterized using various techniques. Structural analysis reveals that U3TeW consists of three [B-α-TeW9O33]8- fragments encapsulating a central heterometallic NaWU3O10(H2O)3 cluster with a trigonal bipyramidal geometry. Furthermore, U3TeW exhibits remarkable photocatalytic activity in the visible-light-driven hydroacylation of dialkyl azodicarboxylates, enabling efficient C-N bond formation with excellent yields and broad substrate scope. This study provides a rare example of U(VI)-incorporated polyoxometalate-based photocatalysts applied in the field of C-H functionalization.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...
