the 2-(methylamino) pyridine, l, reacts with cucl in thf to give hexameric copper (i) complex, [cucl(l)]6. the molecular structure has been determined by using single-crystal x-ray diffraction method. the complex crustallizes in the monoclinic space group p21/n with four molecules per unit cell. the unit cell dimensions are a = 8.3495 (15), b = 15.622 (6), and c = 17.030(4) å with b= 98.55 (2)°...

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 [ni (map)...

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.

2-(Methylamino) pyridine (HMAP) reacts with MeLi in THF and generates the lithium salt (LiMAP). Further reaction of [Cu(TMEDS)2][CuCl2] (TMEDA=tetramethylethylenediamine) with one equivalent of this ligand in THF leads to the formation of a yellow dimeric Cu(I) complex, [Cu(MAP)]2. Analytical data, molecular weight, and magnetic susceptibility measurements, ...

2-(methylamino) pyridine (hmap) reacts with meli in thf and generates the lithium salt (limap). further reaction of [cu(tmeds)2][cucl2] (tmeda=tetramethylethylenediamine) with one equivalent of this ligand in thf leads to the formation of a yellow dimeric cu(i) complex, [cu(map)]2. analytical data, molecular weight, and magnetic susceptibility measurements, confirm the formula [cu(map)]2 .

Dimeric metal complexes can often exhibit coupling interactions via bridging ligands. In this report, we present two Re(CO)3 dimers, where the metals are linked via a bis(pyca) hydrazine (pyca = pyridine-2-carbaldehyde imine) Schiff base ligand. For the dimeric compounds 4 and 5, we observe strong coupling across the dimer as measured by cyclic voltammetry: ∼480 mV separations between the first...

In the present study, a series of 2-substituted-pyridines were synthesized and characterized by IR, (1)H-NMR and Elemental Analysis. The compounds were assayed against seizures induced by maximal electro shock (MES) and pentylenetetrazole (scMet). Neurologic deficit was evaluated by the rotarod test. The decrease in the elevated motor activity by introceptive chemical stimuli (amphetamine antag...

Aminopyridines such as 4-aminopyridine (4-AP) are widely used as voltage-activated K(+) (Kv) channel blockers and can improve neuromuscular function in patients with spinal cord injury, myasthenia gravis, or multiple sclerosis. Here, we present novel evidence that 4-AP and several of its analogs directly stimulate high voltage-activated Ca(2+) channels (HVACCs) in acutely dissociated neurons. 4...
