Immiscible liquid-liquid interfaces provide unique double phase regions for the design and construction of nanoscale materials. Here, we reported Ag(I)-directed growth of metal-organic complex nanocrystals by using AgNO3 as a connector in the aqueous solution and bidentate ligand of 1,4-bis(9-O-dihydroquininyl)anthraquinone [(DHQ)2AQN] and its enantiomer of (DHQD)2AQN in the chloroform solution...
The title compound, [Cu(C6H4NO2)2(C16H38N6)] has been synthesized and characterized by structure analysis based on synchrotron data and by FT-IR spectroscopy. The asymmetric unit consists of half of the Cu(II) complex, the other half being completed by inversion symmetry. The Cu(II) ion has a tetra-gonally distorted octa-hedral coordination sphere with four secondary N atoms of the aza-macrocyc...
As part of an ongoing study to construct a molecular Turing machine in which a polymer chain is encoded via allosteric information transfer between macrocyclic complexes, we describe the thermodynamic and kinetic characterization of a multicomponent self-assembled system based on a zinc porphyrin macrocyclic compound, a bidentate ligand (1,4-diazabicyclo[2.2.2]octane, DABCO), and a viologen-sub...
In the title complex, [Ag(C(16)H(14)N(2))(2)]NO(3), the geometry around the Ag(I) ion is T-shaped with two short Ag-N bonds to the pyrazole ligand and one long Ag-O bond to the nitrate anion. The crystal structure is stabilized by inter-molecular N-H⋯O, C-H⋯O and C-H⋯π inter-actions.
The structure of the title complex, [Ag(C(12)H(8)N(2))(C(18)H(15)P)]CF(3)SO(3), is based on a distorted trigonal-planar N(2)P coordination of the Ag(I) ion, provided by two N atoms of the bidentate phenanthroline ligand and one P atom of the triphenyl-phosphine ligand. The phenanthroline ligand and one phenyl ring of the triphenyl-phosphine ligand almost lie in one plane (maximum deviation = 0....
Glycolytic interconversion of phosphoglycerate isomers is catalysed in numerous pathogenic microorganisms by a cofactor-independent mutase (iPGM) structurally distinct from the mammalian cofactor-dependent (dPGM) isozyme. The iPGM active site dynamically assembles through substrate-triggered movement of phosphatase and transferase domains creating a solvent inaccessible cavity. Here we identify...
The reaction of 1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene (bib) with silver(I) nitrate in a 1:1 molar ratio generates the metallacyclic title complex, [Ag(2)(C(12)H(14)N(4))(2)](NO(3))(2)·2H(2)O, in which the bib ligand displays a cis configuration. Each bib ligand acts as a bidentate bridging ligand connecting a pair of Ag(I) ions to form a [2 + 2] metallamacrocycle in which the Ag⋯Ag dist...
