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 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 ...
