Bifunctional W/NH Cuboidal Aminophosphino W3S4 Cluster Hydrides: The Puzzling Behaviour behind the Hydridic-Protonic Interplay
Wiley (2021-09-22)The novel [W3S4H3(edpp)3]+ (edpp=(2-aminoethyl)diphenylphosphine) (1+) cluster hydride with an acidic −NH2 functionality has been synthetized and studied. Its crystal structure shows the characteristic incomplete W3S4 ... -
Caught in Action: X-ray Structure of Thymidylate Synthase with Noncovalent Intermediate Analog
American Chemical Society (2021-04-08)Methylation of 2-deoxyuridine-5′-monophosphate (dUMP) at the C5 position by the obligate dimeric thymidylate synthase (TSase) in the sole de novo biosynthetic pathway to thymidine 5′-monophosphate (dTMP) proceeds by forming ... -
Crystal structure and spectroscopy studies of the thulium acid pyrophosphate HTmP2O7·3H2O
Elsevier (2020-09-02)Crystals of HTmP2O7·3H2O were prepared via a soft chemistry route. Its crystal structure was solved from single-crystal diffraction data. The compound crystallises in the triclinic space group P-1, with the unit cell ... -
Crystal structure and theoretical study of IR and 1H and 13C NMR spectra of cordatin, a natural product with antiulcerogenic activity
Wiley (2008)Cordatin is a furan diterpenoid with a clerodane skeleton isolated from Croton palanostigma Klotzsch (Euphorbiaceae). This natural product shows significant antiulcerogenic activity, similar to cimetidine (Tagamet®), a ... -
Stabilization of Nanoparticles Produced by Hydrogenation of Palladium–N-Heterocyclic Carbene Complexes on the Surface of Graphene and Implications in Catalysis
American Chemical Society (2018)Palladium nanoparticles (NPs) have been obtained by decomposition of well-defined palladium complexes noncovalently anchored onto the surface of reduced graphene oxide. Morphological analysis by microscopy showed the ... -
Stereoisomerization of α-hydroxy-β-sulfenyl-α,β-dimethyl naphthoquinones controlled by nonbonded sulfur–oxygen interactions
Elsevier (2013-03)The anti α-hydroxy-β-sulfenyl-α,β-dimethyl naphthoquinones isomerize in basic media into syn/anti mixtures of isomers, giving the syn isomer as the major product. Conversely, anti α-hydroxy-β-alkoxy-α,β-dimethyl naphthoquinones ... -
Structural study, spectroscopic characterization, DFT calculations and electrical properties of manganese (II) organic-inorganic hybrid material (C8H14N2)2[MnCl4(H2O)2]Cl2
Elsevier (2023-01-13)The new organic-inorganic compound, (C8H14N2)2[MnCl4(H2O)2]Cl2 denoted (1), crystallizes at room temperature in the monoclinic system, P21/c space group. The structure exhibits an alternate organic-inorganic layered stacking ... -
Surface versus Bulk Currents and Ionic Space-Charge Effects in CsPbBr3 Single Crystals
American Chemical Society (2022-04-25)CsPbBr3 single crystals have potential for application in ionizing-radiation detection devices due to their optimal optoelectronic properties. Yet, their mixed ionic–electronic conductivity produces instability and hysteretic ... -
The P. aeruginosa effector Tse5 forms membrane pores disrupting the membrane potential of intoxicated bacteria
Nature Research (2022)The type VI secretion system (T6SS) of Pseudomonas aeruginosa injects effector proteins into neighbouring competitors and host cells, providing a fitness advantage that allows this opportunistic nosocomial pathogen to ...
