In the title compound, [CdCl(2)(C(11)H(17)N(3))], the Schiff base acts as an N,N',N''-tridentate ligand towards the Cd(II) ion. Two Cl atoms complete a distorted square-pyramidal geometry around the metal atom. In the crystal, a C-H⋯Cl inter-action connects pairs of mol-ecules into centrosymetric dimers.
N, N΄-3, 4-di(methylamino)-1, 2, 5-oxadiazole (1f) was prepared by dehydration of N, N΄-3, 4-di(methylamino)glyoxime (2f) in aqueous potassium hydroxid at 170-180 ˚C. Under similar conditions N, N΄-3, 4-di(benzylamino)-1, 2, 5-oxadiazole (1c) and N, N΄-3, 4-di(isopropylamino)...
In the title mol-ecule, C29H29N5, the indole ring systems are essentially planar, with maximum deviations of 0.020 (2), 0.023 (2) and 0.016 (2) Å. The dihedral angles formed between the mean planes of the three indole ring systems are 38.08 (7), 89.64 (8) and 58.28 (8)°. In the crystal, mol-ecules are connected by N-H⋯N hydrogen bonds, forming inversion dimers. An intra-molecular N-H⋯N hydrogen...
The asymmetric unit of the title compound, [CdCl(2)(C(12)H(18)N(4)O(2))(2)]·H(2)O, contains one water mol-ecule and two halves of a [CdCl(2)(BIEE)(2)] complex mol-ecule {BIEE is 1,2-bis-[2-(1H-imidazol-1-yl)eth-oxy]ethane}, with the Cd(II) atoms lying on inversion centres. Each metal atom displays an elongated octa-hedral coordination geometry provided by two trans-arranged chloride anions and ...
A series of 2-(p-substituted benzylidene)-3-(5-ethyl-1, 3, 4-thiadiazol-2-yl) thiazolidin-4-ones were synthesized by the reaction of Schiff’s bases of N-(p-substituted benzylidene)-5-ethyl-1, 3, 4-thiadiazole-2-amines with thioglycolic acid in 1, 4-dioxane as solvent and studied for their in vitro antibacterial activity. Reaction of thiosemicarbazide with propanoic acid in presence of concentra...
