New 5-[1-(anthracen-9(10H)-ylideneamino)-2-(1H-imidazol-5-yl)ethyl]-1,3,4-thiadiazol-2-amine 3 has been synthesized from condensation reaction of N-anthracen-9(10H)-ylidenehistidine 2 with thiosemicarbazide in phosphorusoxy chloride. The prepared compounds were characterized by FTIR spectroscopy, electronic spectroscopy, NMR and NMR. Preliminary in vitro tests for fungicidal activity show that ...
The centrosymmetric mol-ecule of the title compound, [Zn(C(16)H(11)N(6))(2)(H(2)O)(2)], contains one Zn(2+) ion located on a center of symmetry, two 3-[4-(1H-imidazol-1-yl)phen-yl]-5-(pyridin-2-yl)-1H-1,2,4-triazol-1-ide (Ippyt) ligands and two coordinating water mol-ecules. The Zn(II) ion is six-coordinated in a distorted octa-hedral coordination geometry by four N atoms from two Ippyt ligands...
In the title compound, [HgBr(2)(C(15)H(17)N(5))], the Hg(II) ion is tetra-hedrally coordinated by two N atoms of the N-[1-(1H-benzimidazol-2-yl)ethyl-idene-κN]-3-(1H-imidazol-1-yl)propan-1-amine ligand, and two bromide anions. Inter-molecular benzimidazole-imidazole N-H⋯N hydrogen bonds link the mol-ecules into helical chains along the b-axis direction and C-H⋯Br hydrogen bonds link these chain...
A novel series of 7,7-diphenyl-1,2-dihydroimidazo[2,1-c][1,2,4]triazin-6(7H)-one 6a-h, were easily prepared via reactions of novel 2-hydrazinyl-4,4-diphenyl-1H-imidazol-5(4H)-one (2) with hydrazonoyl halides 3a-h. In addition, we also examined the reaction of compound 2 with commercially available active methylene compounds to afford new pyrazoles containing an imidazolone moiety, expected to b...
Co(II) nitrate reacts with potassium 5-[(2-methyl-1H-imidazol-1-yl)methyl]isophthalate (K2L) under hydrothermal conditions to yield a new complex [Co(L)(H2O)] (1). In the presence of 2-(pyridin2-yl)-1H-benzo[d]imidazole (pybim) as auxiliary ligand, complex [Cd(L)(pybim)] (2) can be obtained using Cd(NO3)2. Complexes 1 and 2 have been characterized by single-crystal and powder X-ray diffraction,...
In the polymeric title complex, [CdCl(2)(C(12)H(13)N(5))](n), the Cd(II) atom is five-coordinated by two N atoms from two bridging 1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole (bmei) ligands, two bridging Cl atoms and one terminal Cl atom in a distorted trigonal-bipyramidal geometry. The Cd(II) atoms are connected alternately by the Cl atoms and bmei ligands, leading to a zigzag chain...
In the hydro-thermally prepared title coordination polymer, [Ni(C(2)H(6)NO(3)S)(2)(C(12)H(10)N(4))](n), the Ni(II) ion and the 1,4-bis-(1H-imidazol-1-yl)benzene ligand occupy special positions on inversion centers. The metal ion shows a slightly distorted octa-hedral coordination geometry, being linked to two N atoms of two 1,4-bis-(imidazol-1-yl)benzene ligands and to two O and two N atoms of ...
In the title compound, C14H12N4, the dihedral angle between the indole ring system (r.m.s. deviation = 0.010 Å) and the imidazole ring is 77.70 (6)°. In the crystal, mol-ecules are linked by C-H⋯N hydrogen bonds. One set of hydrogen bonds forms an undulating chain running parallel to the b-axis direction, while the other undulating chain is parallel to the c-axis direction. In combination, (100...
The dinuclear title complex, [Cd(2)I(4)(C(12)H(13)N(5))(2)], lies on a crystallographic center of inversion. The Cd(II) atom is four-coordinated by two N atoms from two 1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole (bmei) ligands and two terminal I atoms in a distorted tetra-hedral coordination environment. The Cd(II) atoms are connected to each other by two bridging bmei ligands. The ...
Çalışmamızda yeni antikanser ilaçlar geliştirmek üzere bazı benzimidazol-tiyadiazol türevi bileşikler tasarlanmış ve yapıları 1H-NMR,13C-NMR elemental analiz spektral verileriyle kanıtlanmıştır. Bileşiklerin sitotoksik aktiviteleri HT29 hücre hattı üzerinde MTT yöntemi kullanılarak referans bileşik florourasilile kıyaslanarak değerlendirilmiştir. Ayrıca, bileşiklerin seçiciliklerini tespit etme...
