The siderophore-based extraction of iron from the soil by bacteria is proposed as a model for a new separation methodology labeled the soil poultice, a molecular device that would selectively retrieve the complex of a targeted metal ion. In this first feasibility study we describe the synthesis and characterization of molecularly imprinted polymers based on noncovalent interactions, and their a...

In the mononuclear title salt, [Ag(C3H8N2S)(C18H15P)3](CH3COO), the Ag(I) ion exhibits a distorted tetra-hedral coordination sphere defined by three P atoms from three tri-phenyl-phosphane ligands and one S atom from a 1,3-di--methyl-thio-urea ligand. In the crystal, the acetate anion is linked with the complex cation via duplex N-H⋯O hydrogen bonds [graph-set motif R (2) 2(8)].

The title compound, [Ag(2)(NCS)(2)(C(14)H(38)B(10)P(2))(2)], was synthesized by the reaction of 1,2-bis-(diiso-propyl-phos-phan-yl)-1,2-dicarba-closo-dodeca-borane with AgSCN. The diisopropyl-phosphanyl-closo-carborane ligand is coordinated in a bidentate manner to the Ag(I) atom through the two P atoms. The coordination of the Ag(I) atom is distorted tetra-hedral, in which two vertices are for...

This work presents a simple synthesis of tetraaza macrocyclic Schiff base ligand (C40H28N4), its complex [(C40H28N4)@Fe(II)], and novel magnetite Fe3O4NPs incorporated inside cavity [(C40H28N4)@Fe3O4NPs] by the co-precipitation method in order to obtain well-dispersed nanoparticles, controlled size prevent aggregation Fe3O4 NPs due strong dipole–dipole magnetic attractions interactions between ...

here, we report the synthesis of a schiff-base mixed-ligand complex of cadmium(іі) in bulk and nano-scales via the precipitation and sonochemical methods, respectively. the complex formula is [cd(3-bpdh)(3-bpdb)cl2]n (1), where the ligands are 3-bpdh = 2,5-bis(3-pyridyl)-3,4-diaza-2,4-hexadiene and 3-bpdb = 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene. the structure of mixed-ligand complex (1) wa...

As CTL adhere to and lyze their targets, they extract cognate Ag-MHC and represent this on their own cell surface. Whether such self-presented cognate Ag stimulate the TCR of a CTL is uncertain. To analyze this, we examined TCR capping in response to self-presented Ag. We found that OVA peptide-specific OT-1 CTL that were pulsed with cognate peptide Ag did not cap their TCR, implying that the a...

Two silver(I) coordination architectures with the flexible ligand 1,6-bis(phenylthio)hexane (L) have been synthesized and their crystal structures determined by X-ray diffraction analysis. Different frameworks were observed in the two complexes due to variation of the counter anions. The dinuclear complex [Ag(L)(ClO4)]2 (1) has a cage structure with the perchlorate anions coordinated to the two...

In this study, the new benzimidazolium salt (1) containing ether functionalized alkyl group as NHC ligand precursor was synthesized. Ag-NHC complex (2) synthesized by interaction with Ag2O of precursor. The Au-NHC [AuCl(PPh3)] complex. structures prepared all compounds were characterized different spectroscopic methods.

Copper(I) complexes of the ligand cis-1,3,5-tris(cinnamylideneamino)cyclohexane (L) have been prepared from a versatile precursor complex, [Cu(I)(L)NCMe]BF4, which incorporates a labile acetonitrile ligand that can be exchanged to give a range of new Cu(L)X complexes (where X = Cl, Br, NO2, SPh). 1H NMR spectra and X-ray structures of the Cl, Br and NO2 complexes show L coordinated in a symmetr...

In the dinuclear title complex, [Ag2Cl2(C7H8N2S)(C25H22P2)2]·0.5CH3CN, each Ag(I) ion displays a distorted tetra-hedral coordination geometry with two P atoms from two bis-(di-phenyl-phosphan-yl)methane (dppm) ligands, one bridging chloride ion, one terminal chloride ion and one terminal S atom from the N,N'-phenyl-thio-urea (ptu) ligand. The dppm ligands and the bridging chloride ion force the...
