Summary: This study investigates the reduction reactions of Co-II, Fe-II, and Ni-II complexes and reveals their different behaviors in the presence of a reductant. The yield of the Co-II complex is 70%, while the Fe-II complex does not yield identifiable compounds. On the other hand, the reduction of the Ni-II complex leads to the isolation of a novel Ni-0 trimer.

Summary: A ligand coupling reaction occurred during the reduction of a Co-II complex supported by a diisopropylphosphinoquinoline (L) ligand, leading to the formation of a (PNNP) supported Co-II complex. The behavior of various 3d metal complexes in the presence of a reductant was observed, and a novel Ni-0 trimer was isolated.

Summary: Hydro(solvo)thermal reactions of cobalt(n) salts, organic ligands, and solvent systems have been studied, resulting in the synthesis of four different coordination compounds. The structures of these compounds have been characterized using single-crystal X-ray diffraction. The experimental results demonstrate the significant influence of reaction conditions on structural diversity.

Summary: Nowadays, there are studies on the design and synthesis of new catalysts for olefin oligomerization and polymerization, with non-toxic metals and high catalytic activities. Transition metal complex compounds, such as Fe(II), Cr(III), and Zr(II), that contain pyridine or quinoline ligands have been found to exhibit moderate catalytic activity in ethylene and propylene polymerizations. In this study, a new cobalt(II) complex compound with bis(5-chloroquinolin-8-olato)-bis(pyridine) ligands was synthesized and tested for its catalytic activity in reactions of 2-chloro-2-propen-1-ol and norbornene oligomerizations. The results showed that the activated bis(5-chloroquinolin-8-olato)-bis(pyridine)-cobalt(II) catalyst can promote the formation of oligomers in nitrogen atmosphere, at atmospheric pressure, and at room temperature, demonstrating moderate catalytic activity in norbornene oligomerization and low catalytic activity in 2-chloro-2-propen-1-ol oligomerization.

Summary: Divalent carbon(0) species, carbones, with two lone pairs of electrons have been prepared in this study. The first known stable and isolable free bis-(carbone) pincer framework was synthesized, which serves as an effective scaffold for forming monometallic and trinuclear heterometallic complexes. Quantum-theoretical analyses showed that the stability of these complexes is mainly attributed to the four lone pairs of electrons within the bis-(carbone) framework, rather than metal-metal interactions.

Summary: New triazine ligands C3H5N5O (L1) and C5H5N5O3 (H(2)L2) were synthesized using diaminoguanidine hydrochloride and glyoxylic acid as precursors. The corresponding cobalt complex, [Co-3(L1)(2)(L2)(4)]center dot 4H(2)O (1), was synthesized through a one-pot green synthesis process and characterized using spectroscopic and elemental analysis methods. The cobalt complex exhibited promising antioxidant activity, protein binding, and cytotoxicity towards MCF-7 cancer cells, indicating its potential as a therapeutic agent.

Summary: The designing and synthesis of luminescent metal-organic frameworks (LMOFs) as sensors for molecule and ion detection is an active area of research. This study successfully synthesized four different three-dimensional (3D) LMOFs and analyzed their structures and optical properties. The experimental results showed that these LMOFs can be used as luminescent sensors for detecting metal ions, oxyanions, and organic solvents in an aqueous environment.

Summary: A novel catalytic system based on copper(I) and chiral bis(phosphine) dioxides has been developed for the arylation of silyl enol ethers, yielding enolizable alpha-arylated ketones with high yields and enantiomeric excess up to 95%. This method is applicable to noncyclic ketones and complements other palladium-catalyzed approaches. Optimization of ligand structure was achieved through rational design driven by correlation analysis, and preliminary mechanistic hypotheses were evaluated to understand the role of chiral bis(phosphine) dioxides.

Summary: Three new metal-organic framework (MOF) compounds were synthesized by assembling metal ions (Cu(II) and Co(II)) with H3tci and two different N-donor ligands (btx and biip) under solvothermal conditions. The structure analysis showed that compound 1 is a 1D coordination polymer, compound 2 is a 2D layered structure, and compound 3 is a 3D framework.

Summary: Heteroleptic U(III) complexes supported by bis(cyclopentadienyl) frameworks were synthesized and evaluated as precursors to U(II) complexes. The complexes were compared with other related compounds, and their electrochemical behavior was studied, revealing redox couples for U(IV)/U(III) and U(III)/U(II) transitions. The targeted U(II) complexes were analyzed using density functional theory, showing a 5f(3)6d(1) electron configuration as the ground state in each case.
