Double loading of ZnCl(2) by polytopic ligands which co-extract Zn(2+) and tetrachloridozincate.
Combining cation- and anion-binding functionalities in a salen-type extractant leads to multiple loading of ZnCl(2). Zn(ii) cations are bound by the salen N(2)O(2)(2-) donor set, and chlorozincate anions are associated with protonated pendant amine groups.
متن کاملThe preparation and characterisation of ruthenium cyanovinylidene complexes.
Reactions of half-sandwich ruthenium metal acetylide complexes with 1-cyano-4-dimethylaminopyridinium salts afford complexes containing mono- or di-cyanovinylidene ligands; the procedure can be adapted to permit the simple synthesis of a cyanoacetylide complex, via the in situ deprotonation of a primary cyanovinylidene complex.
متن کامل1-Methylpiperazine-1,4-diium tetrachloridozincate hemihydrate
The crystal structure of the title compound, (C(5)H(14)N(2))[ZnCl(4)]·0.5H(2)O, is built up from discrete 1-methyl-piperazine-diium cations with chair conformation, tetrahedral tetrachloridozincate anions and uncoordinated solvent water mol-ecules linked together by three types of inter-molecular hydrogen bonds, viz. N-H⋯Cl, N-H⋯O and O-H⋯Cl.
متن کاملWhole glucan particles as a vaccine against systemic coccidioidomycosis.
We reported previously that yeast-derived whole glucan particles (WGPs), with or without conjugation to BSA, used as a vaccine protected against systemic aspergillosis in mice. Here, we examined their utility as a potential vaccine against coccidioidomycosis. WGPs were prepared from Saccharomyces cerevisiae; conjugation with BSA (WGP-BSA) was done using 1-cyano-4-dimethylaminopyridinium tetrafl...
متن کاملBis(1,10-phenanthrolin-1-ium) tetrachloridozincate monohydrate
In the crystal structure of the title compound, (C12H9N2)2[ZnCl4]·H2O, the two independent 1,10-phenanthrolinium cations are bridged by the water mol-ecule and the tetrahedral tetrachloridozincate anion via N-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds, forming chains along [100]. The chains are linked via C-H⋯Cl hydrogen bonds and a number of π-π inter-actions [centroid-centroid distances vary from ...
