An octahedral cobalt(III) complex, trans-[(Me2bpb)Co(bzlan)2]ClO4 (1), with H2Me2bpb = N,N’-(4,5-dimethyl-1,2-phenylene)dipicolinamide and bzlan = benzylamine, has been synthesized and characterized by elemental analyses, IR, UV-Vis, and 1H NMR spectroscopy. The structure of this complex has been determined by X-ray crystallography. The Me2bpb2– is a di-anionic tetradentate ligand furnishing a ...

The ionic title complex, [Cu(C(4)H(13)N(3))(2)](2)[Cr(NCS)(4)(NH(3))(2)](3)(NCS)·14C(2)H(6)OS·H(2)O, consists of complex [Cu(dien)(2)](2+) cations [dien is N-(2-amino-eth-yl)ethane-1,2-diamine], com-plex [Cr(NCS)(4)(NH(3))(2)](-) anions, an NCS(-) counter-anion and uncoordinated dimethyl sulfoxide (DMSO) and water solvent mol-ecules. One of the Cr atoms lies on an inversion center, while the se...

By using quantum mechanical DFT calculations, the most probable structure of the bambus[6]uril x NO3(-) anionic complex species was derived. In this complex having C3 symmetry, the nitrate anion NO3(-), included in the macrocyclic cavity, is bound by twelve weak hydrogen bonds between methine hydrogen atoms on the convex face of glycoluril units and the considered NO3(-) ion.

Objective(s): Early diagnosis of cancer using noninvasive imaging techniques has been discussed in several recent studies. The present study aimed to assess the synergistic effects of iodixanol-conjugated polyethylene glycol (PEG)-citrate (anionic linear globular) dendrimer G2 on MCF-7 breast cancer cells and human embryonic kidney 293 (HEK293) cells. Materials and Methods: PEG-citrate de...

Glassy carbon electrodes (GCE) modified by a bilayer of phospholipids (BLM) have been used to monitor the passage redox probes and ferrocene-labelled peptides across lipid membranes an anionic (DOPG) or zwitterionic (globally neutral DPhPC) phospholipid. The gel-phase DPhPC showed strong association with like ferrocene methanol but expelled positively negatively charged species, as observed on ...

Previous efforts to prepare halogen-bridged anionic complexes of Hg(II) by the method of "etherohalogenosis" [2] met with failure in this department. Recently, however, we were able to isolate three new salts having the [Hg2ls]~, [Hg2le]2and [Hg3l8]~ ions; the present paper reports the preparation and characterization of these salts. Very few preparative and spectroscopic studies have been made...
