The syntheses, crystal structures and magnetic properties are described for a {Co16} cluster [Co(II)16O(OH)2(bha)12(PhCO2)4(Phen)2(MeOH)4]·2MeOH (1) and a 1-D Mn(II) chain complex [Mn(Hbha)2]n·(2MeOH)n (2) (H2bha = benzohydroxamic acid; Phen = 1,10-phenanthroline). The 1 : 1 : 0.5 reaction of Co(O2CMe)2·4H2O, H2bha and 1,10-phenanthroline in MeOH at 100 °C under autogenous pressure gave cluster...
A new synthetic method for polynuclear lanthanoid complexes that are embedded in molecular polyoxotungstates has afforded the highest nuclearity polyoxometalate-encapsulated Gd complex and the first decanuclear Yb complex of any sort to be structurally characterized.
The water oxidation half-reaction is considered the bottleneck in development of technological advances to replace fossil fuels with sustainable and economically affordable energy sources. In natural photosynthesis, occurs oxygen evolving complex (OEC), a manganese-oxo cluster {Mn4CaO5} cubane-like topology that embedded within redox-active protein environment located photosystem II (PS II). Th...
The ability of mononucleating and dinucleating macrocylic polyamines and their novel nickel, copper and zinc complexes to induce the left-handed form of poly d(GC) was evaluated. The influence of the nuclearity, the presence or absence of metals ions, the linker length in the case of dinucleating ligands and the metal ion was determined. Almost all dinuclear metal complexes efficiently induced ...
We study the semigroup C?-algebra of a positive cone P weakly quasi-lattice ordered group. That is, is subsemigroup discrete group G with P?P?1={e} and such that any two elements common upper bound in also have least bound. find sufficient conditions for to be nuclear. These involve idea generalised length function, called “controlled map”, into an amenable Here we give new definition controlle...
Subnanometer catalysts offer high noble metal utilization and superior performance for several reactions. However, understanding their structures properties on an atomic scale under working conditions is challenging due to the large configurational space. Here, we introduce efficient multiscale framework predict stability exposed adsorbate. The integrates a comprehensive toolset including densi...
This article covers 50 years of coordination chemistry transition metal complexes and metal-sulfur aggregates involving thiolate-incorporating ligands by reviewing selected examples. The studies in the sulfur-rich have been undoubtedly triggered fed concomitant development bioinorganic chemistry, particularly iron-sulfur enzymes. review is broken down five sections, which examine increasing nuc...
