A new tetrakis(pyrazolyl)borate ligand bearing triphenylphosphine oxide moieties appended to the 3-position of the pyrazolyl rings is reported and shown to display varied coordination chemistry from tridentate N(2)O coordination with thallium to hexadentate N(3)O(3) coordination with europium.

A coordination-responsive tellurium containing film was fabricated for controlled release. The coordination chemistry between telluride molecules and cisplatin was utilized for the loading of cisplatin, while competitive ligands were used for triggered release. This work could enrich the coordination responsive system and further tune the release kinetics of cisplatin.

The chemistry of N-substituted amine-boranes and their reactivity towards transition metal centres is well established but the chemistry of B-substituted amine-boranes is not. Here we present the coordination chemistry of H2PhB·NMe3 towards a range of Rh(i) fragments with different P-Rh-P ligand bite angles, {Rh(P(i)Pr3)2}(+), {Rh(P(i)Bu3)2}(+), {Rh((i)Pr2P(CH2)3P(i)Pr2)}(+), {Rh(Ph2P(CH2)nPPh2...

Since their discovery by Alfred Werner, coordination complexes have played a very important role in many subdisciplines of chemistry, including inorganic (1–3) and bioinorganic (4, 5) chemistry and polymer (6) and materials science (8, 9). In recent years, the metal–ligand coordination bond has gained importance for the construction of supramolecular complexes and solid-state structures (7–14)....

With the discovery of the phenomenon of single-molecule magnetism, coordination chemists have turned their attention to synthesizing cluster aggregates of paramagnetic ions. This has led to a plethora of coordination clusters with various topologies and diverse magnetic properties. In this paper, we present ways of describing and understanding such compounds as well as outlining a new approach,...

Article Systematic Nomenclature of Organic, Organometallic and Coordination Chemistry. Chemical-Abstracts Guidelines with IUPAC Recommendations Many Trivial Names was published on July 1, 2022 in the journal Chemistry International (volume 44, issue 3).

The essential transition metal ions are avidly accumulated by cells, yet they have two faces: They are put to use as required cofactors, but they also can catalyze cytotoxic reactions. Several families of proteins are emerging that control the activity of intracellular metal ions and help confine them to vital roles. These include integral transmembrane transporters, metalloregulatory sensors, ...

A synthetic route for the formation of 2-[bis(2-trifluoromethylphenyl)phosphinoylmethyl]pyridine N-oxide (1c) and 2-[bis(3,5-trifluoromethylphenyl)phosphinoylmethyl]pyridine N-oxide (1d) was developed and the new ligands characterized by spectroscopic methods and single-crystal X-ray diffraction analyses. The coordination chemistry of 1c was examined with Yb(NO3)3 and the molecular structure of...

This review summarizes the synthesis and coordination chemistry of a series of carboranyl ligands containing N,O donors. Such carborane-based ligands are scarcely reported in the literature when compared to other heteroatom-containing donors. The synthetic routes for metal complexes of these N,O-type carborane ligands are summarized and the properties of such complexes are described in detail. ...
