Summary: The industrialization of organic compound oxidation processes can be accelerated by synthesizing a monometallic dioxomolybdenum(VI) bis-Schiff base complex (MoO2L2) through coordination of 4-hydroxyiminophenol ligand (HL) with cis-MoO2 (2+) ion. A heterogeneous catalyst (MoO2L2@ZnO-TiO2) was prepared by immobilization of MoO2L2 on the surface of ZnO-TiO2 nanostructured particles. Both catalysts showed high catalytic potential and recyclability. Rating: 8/10.

Summary: Fe(III) and Mn(II) complexes with a thiosemicarbazone ligand have been synthesized and characterized. The coordination environments and ground states of the complexes differ, with Fe(III) adopting a distorted octahedral geometry and a doublet ground state, while Mn(II) has a distorted trigonal-prismatic coordination environment and a sextet ground state. DFT calculations provide insights into the spin states, and the antimicrobial and antioxidant activities of the complexes correlate with their electronic structures.
