A series of dimetallic and monometallic Cp*Ir(III) complexes bearing naphthalene-diimide-decorated N-heterocyclic carbene/pyridine [NDI-(NHC-pyridine)] ligands were prepared characterized. The show a C,C-chelating coordination the NHC-pyridine ligand, with pyridine ring ligand bound to metal via cyclometallation rather than by its nitrogen atom, although atom could be achieved subjecting one re...

1. Inhibition by pyridine of reduction of NAD by ethanol in the presence of yeast alcohol dehydrogenase was studied at 25 degrees in 60mm-glycine buffer (K(+), pH9.3). 2. The apparent Michaelis constant for ethanol increases linearly and that for NAD increases non-linearly with pyridine concentration. 3. Rates, v, observed in the presence of pyridine are lower than the values calculated from th...

We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [N...

Abstract Background The heterocyclic compounds particularly pyridine displayed clinical and biological implementation. Pyridine scaffolds have been detected in most relevant drug molecules that included provided a great possibility for treatment. Main text Pyridine-containing increasing importance medicinal application as antiviral, anticholinesterase activities, antimalarial, antimicrobial, an...

In the crystal structure of the title compound, [CuCl(C(5)H(5)N)(4)][N(CN)(2)]·2C(6)H(5)N, the copper(II) cations are coordinated by one chloride anion and four N-bonded pyridine ligands into discrete complexes. The copper(II) cation shows a square-pyramidal coordination environment, with the chloride anion in the apical position. However, there is one additional chloride anion at 3.0065 (9) Å,...

1. Cyanide hemochromogen probably contains one cyanide group per heme group. 2. The equilibrium between pyridine hemochromogen and its components, pyridine and reduced heme, is complicated to an unknown extent by the precipitation of reduced heme and the aggregation of pyridine hemochromogen. 3. These complications were not taken into account in R. Hill's experiments on pyridine hemochromogen. ...
