A new copper(II) complex with a (bdpg-His) ligand was prepared and its structural properties were investigated both in crystalline and in solution states; (bdpg-His) = N,N-bis(2-pyridylmethyl)carnosine methylester. In the solid state, the complex has a dimeric structure, but in solution it partially dissociates into monomeric species, which have an imidazole moiety as an anchor group. This comp...

The title compound, C(18)H(16)N(6)·2CH(3)OH, was prepared by the reaction of 5,5'-bis-(bromo-meth-yl)-2,2'-bipyridine with imidazole. The main mol-ecule lies on an inversion center located at the mid-point of the C-C bond joining the two pyridine rings. The asymmetric unit therefore contains one half-mol-ecule and one methanol solvent mol-ecule. The dihedral angle between the pyridine and imida...

The title compound, C(20)H(22)N(6) (2+)·2PF(6) (-), was prepared by the reaction of 5,5'-bis-(bromo-meth-yl)-2,2'-bipyridine with 1-methyl-imidazole. The main mol-ecule lies on an inversion center located at the mid-point of the C-C bond joining the two pyridine rings. The asymmetric unit therefore contains one half-mol-ecule and one hexa-fluoro-phosphate anion. The dihedral angle between the p...

In the title compound, [Cu(C(8)H(4)O(4))(C(3)H(4)N(2))(2)](n), the Cu(II) atom is four-coordinated by two carboxyl-ate O atoms from two different terephthalate ligands and two N atoms from two imidazole ligands in a slightly distorted square-planar coordination environment. Each terephthalate ligand acts as a bis-monodentate ligand that binds two Cu(II) atoms, thus forming two unique chains ext...

In the present investigation, series of Bis (heterocycle)s bearing pyrazoline in combination of the imidazole derivatives have been synthesized via 1,3-dipolar cycloaddition reactions of N-(nitrobenzyl)-imidazole nitrile imines with different dipolarophiles. All the newly synthesized compounds were characterized and screened for analgesic-anti-inflammatory activities and were compared with the ...

      Two series (a and b) of N- substituted heteroaromatic compounds related to clotrimazole were synthesized. Imidazole ring of the clotrimazole was replaced by 2-methylimidazole in series a, and by 2-methyl-4-nitroimidazole in series b. O-cholortrityl moiety of clotrimazole was also replaced by trityl, mono or dimethoxy trityl. Chemical structures...

In the crystal structure, the title compound, C(12)H(16)N(6)O(6), lies on an inversion centre. The mol-ecule has an anti-periplanar conformation with respect to the C-C bond of the central ethane unit and the two imidazole rings are parallel to each other. The dihedral angle between the imidazole ring and the mean plane of the C and O atoms of the bis-(eth-oxy)ethane group is 76.04 (6)°. The mo...
