Hydrothermal synthesis, crystal structure and electrochemical behavior of two new isomorphic layered vanadates: [M(dpa)V3O8.5] (M = Cu(II) 1 and Zn(II) 2; dpa = 2,2?-dipyridylamine)

Two new isomorphic vanadates, [M(dpa)V3O8.5] (M = Cu2+ 1, Zn2+ 2; dpa = 2,2?-dipyridylamine) have been synthesized hydrothermally. X-ray crystal analysis reveals that vanadates 1 and 2 exhibit a layered structure constructed from {V3O8.5}2- layers inlaid with [M(dpa)]2+ subunits. The {V3O8.5}2- layers consist of ribbon-like chains of edge sharing {VO5} square pyramids bridged through {V2O7} fragments. Electrochemical measurement shows that lithium ions are reversibly intercalated and deintercalated in vanadate 1.

Polymeric zinc complexes with 2,2?-dipyridylamine and different benzenepolycarboxylato ligands: Synthesis, structure, characterization and antimicrobial activity

A series of new zinc complexes containing the 2,2?-dipyridylamine (dipya) ligand and anions of four benzenepolycarboxylic (BPC) acids, namely phthalic (H2pht), isophthalic (H2ipht), terephthalic (H2tpht) and pyromellitic (H4pyr), have been synthesized by ligand exchange reactions. The complexes were characterized based on elemental analysis, FTIR spectroscopy and thermal (TG/DSC) analysis. The complexes were found to have the formulae [Zn(dipya)(pht)] (1), [Zn(dipya)(ipht)]n (2), {[Zn(dipya)(tpht)]¡¤H2O}n (3) and [Zn2(dipya)2(pyr)] (4). Compounds 2 and 3 have been obtained as single crystals and their crystal structures were determined from X-ray diffraction data. In both structures the coordination number of the Zn atoms is five and they are linked by bridging BPC ligands. In 2, the ipht ligand is coordinated in a tridentate manner via chelate and monodentate COO groups, whereas two crystallographically different tpht ligands in 3 are coordinated as bis-chelate and bis-monodentate ligands, respectively. These combined modes of ipht and tpht anions resulted in zigzag chains of 2 and 3. Two-dimensional pseudo-layers in 2 and a three-dimensional network in 3 are governed by hydrogen bonds and C-H?O interactions which are formed between the zigzag chains, and by additional C-H?pi interactions in 3. The antimicrobial activity of complexes 1-4 was screened in vitro against some Gram-positive bacteria (Bacillus subtilis, Enterococcus faecalis, Listeria monocytogenes and Staphylococcus aureus), some Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa and Salmonella enteritidis) and yeast Candida albicans. Complex 2 showed the most potent inhibitory effect against the tested microorganisms.

Dual-participation protecting group solves the anomeric stereocontrol problems in glycosylation reactions

The 2,2-dimethyl-2-(ortho-nitrophenyl)acetyl (DMNPA) group permits, via robust neighboring group participation (NGP) or long distance participation (LDP) effects, the stereocontrolled 1,2-trans, 1,2-cis, as well as beta-2,6-dideoxy glycosidic bond generation, while suppressing the undesired orthoester byproduct formation. The robust stereocontrol capability of the DMNPA is due to the dual-participation effect from both the ester functionality and the nitro group, verified by control reactions and DFT calculations and further corroborated by X-ray spectroscopy.

Discrete FeII spin-crossover complexes of 2,2?-dipyridylamino-substituted s-triazine ligands with phenoxo, cyanophenoxo and dibenzylamino functionalities

Four 2,2?-dipyridylamino-s-triazine-substituted ligands, each of which incorporate different aromatic substituents (phenoxo, 4-CN-phenoxo and benzylamino) with different degrees of bulk and flexibility, have been formed and incorporated into a number of mononuclear FeII complexes of type trans-[FeII(L)2(NCX)2]¡¤solvent (in which X = S, Se and BH3). These ligands were designed to promote pi-pi stacking between complexes. The complexes reported have been comprehensively characterised using single-crystal diffraction techniques in combination with magnetic susceptibility measurements. Light-induced excited spin-state trapping (LIESST) measurements have been performed on selected complexes. Light irradiation has shown the occurrence of a reversible photoswitching process at low temperature. New mononuclear spin-crossover compounds of type trans-[FeII(NCX)2(L)2]¡¤solvent have been synthesised and structurally characterised. The L ligands are chelated to Fe by dipyridylamine groups and have aromatic substituents on the central triazine ring that influence cooperativity effects monitored by magnetic and light-induced excited-state spin trapping (LIESST) measurements.
