In the title salt, (C7H7N2)2[CuCl4]·2H2O, the Cu2+ cation is coordinated by four Cl atoms and adopts a distorted tetra-hedral geometry. Two mol-ecules of imidazo[1,2-a]pyridine are protonated ensuring electrical neutrality. O-H⋯Cl and N-H⋯O hydrogen bonds link the organic and the inorganic moieties, leading to a self-organized hydrated hybrid structure.
متن کاملDesign and One-Pot Synthesis of (1H, 3H) Imidazo[4,5-b] Pyridines: Novel Therapeutic Agents Against M. Tuberculosis
Prevalence to the various biological activities of imidazo[4,5-b] pyridine nucleus has promoted us for an attempt of one pot synthesis of (1H, 3H) imidazo [4,5-b] pyridines (desazopurines) as inhibitors of Lumazine synthase in M. tuberculosis (PDB 2C92). Major advantage of Lumazine synthase enzyme behind consideration as target protein in docking study is its absence in mammalian cell but prese...

In the mol-ecule of the title compound, C(15)H(11)ClN(2)O(2), the nine-membered heterobicycle is approximately planar [largest deviation from least-squares plane = 0.012 (2) Å] and forms a dihedral angle of 51.14 (8)° with the plane of the 4-chloro-phenyl group. There is a non-classical intra-molecular hydrogen bond between the pyridine α-H atom and the O atom of the benzoyl group. The crystal ...

The side product of the cyclo-condensation reaction between ethyl benzimidazole-2-carboxyl-ate and the nitrile imine of the corresponding hydrazonyl chloride, C20H11BrClN5O, crystallized in two crystal forms. Form (1) is a co-crystal of the target compound (without any chlorine substituent) and a side product containing a Cl atom in position 2 of the bromo-phenyl group, C20H12BrN5O·0.143C20H11B...
