Metronidazole (MET) [systematic names: 1-(2-hy-droxy-eth-yl)-2-methyl-5-nitro-1H-imidazole and 2-(2-methyl-5-nitro-1H-imidazol-1-yl)ethanol] is a medication that is used to treat infections from a variety of anaerobic organisms. As with other imidazole derivatives, metronidazole is also susceptible to protonation. However, there are few reports of the structures of metronidazolium derivatives. ...

The cation of the title compound, C(14)H(14)N(3) (+)·I(-), is non-planar, the dihedral angle between the benzimidazole and the 1-methyl-pyridinium planes being 37.4 (2)°. The crystal structure is stabilized by weak π-π stacking inter-actions, the centroid-centroid distances between 1-methyl-imidazole and benzimidazole planes being 3.678 (4) Å.

Infinite chains connected by N-H...N hydrogen bonding form the primary packing motif in two closely related 4-nitroimidazole derivatives, viz. 5-bromo-2-methyl-4-nitro-1H-imidazole, C(4)H(4)BrN(3)O(2), (I), and 2-methyl-4-nitro-1H-imidazole-5-carbonitrile, C(5)H(4)N(4)O(2), (II). These chains are almost identical, even though in (II) there are two symmetry-independent molecules in the asymmetri...

A promising imidazole compound was synthesized through the following route. The reaction of 5-methyl-2-phenyl-1H-imidazole-4-carbohydrazide (1) with carbon disulfide and potassium hydroxide in ethanol (80%) afforded salt (2). Refluxing (2) phenacyl bromide (3) ethanol/water (1:1) gave 2-((5-(5-methyl-2-phenyl-1H-imidazol-4-yl)-1,3,4-oxadiazol-2-yl)thio)-1-phenylethan-1-one (4) a 76% yield. stru...

Computational chemistry has shown that backbone-alkylated imidazoles ought to be efficient ligands for transition metal catalysts with improved carbene-to-metal donation. In this work, such alkylated imidazoles were synthesized and complexed with silver(I) by means of an eight/nine-step synthetic pathway we devised to access a new class of biologically active silver complexes. The synthesis inv...

A water-accelerated multi-component synthesis of organic target molecules was used as a key method for the preparation of cyclopentadiene derivatives. The three-component condensation reactions of primary amines with alkyl propiolates in the presence of N-methylimidazole in water at room temperature were developed as efficient and clean green synthetic procedures for the high-yielding preparati...

The new diclofenac-based cobalt (II) complex, namely bis {2- [2-(2,6-dichloro anilino) phenyl] acetato-κ'O, O'} (2-methyl-1H-imidazole-κN3cobalt has been synthesized and characterized by FT–IR, UV spectroscopies single crystal X-ray diffraction techniques. title complex crystallizes in the monoclinic space group I2/a with a = 19.0546(8) Å, b 13.7167(8) c 14.7165(7) 90˚, Å g 90˚ Z=4. According t...

We present a high yield synthesis of 1-ethyl-3-methyl-imidazole-2-chalcogenones from readily available imidazolium-2-carboxylate zwitterions NHC−CO2 and elemental chalcogens. In sharp contrast to previous syntheses for corresponding thiones selones imidazolium salts bases our reactions proceed fast with full instead low conversion selectivity, decarboxylation is the driving force. Furthermore, ...

The reaction between [Pt(terpy)Cl]·2H(2)O (terpy = 2',2'':6',2''-terpyridine) and 1-methyl-imidazole (MIm) in the presence of two equivalents of AgClO(4) in nitro-methane yields the title compound, [Pt(C(15)H(11)N(3))(C(4)H(6)N(2))](ClO(4))(2)·CH(3)NO(2). The dicationic complexes are arranged in a staggered configuration. The torsion angle subtended by the 1-methyl-imidazole ring relative to th...
