Two Stages

Eliminating all kinds of harmful organisms is an important task in agriculture, food production, and human life. Quinone oximes and their salts are good bioactive compounds to attain this aim. The alkali metal salts of quinone mono- and dioxime have been synthesized by the reaction of the corresponding quinone oxime with alkali metal hydroxide. The divalent metal salts have been obtained in two stages. The first stage is the synthesis of the sodium salt of the quinone oxime. The second step is the reaction of the latter with a divalent metal salt. Copper and zinc salts of [(4-oxocyclohexa-2,5-dien-1-ylidene)amino]oxidanide have the highest insecticidal activity against the housefly and rice weevil. The death index is 90–100%. Copper {[2-methyl-4-oxo-5-(propan-2-yl)cyclohexa-2,5-dien-1-ylidene]amino}oxidanide shows good activity against Phytophthora infestans. Inhibition of the growth and development of the Phytophthora infestans is 80%.

Intermolecular Hydrogen Bonds

Three new manganese(II), lead(II) and cadmium(II) coordination complexes have been prepared by reaction of N-(1H-tetrazol-5-yl)cinnamamide (HNTCA) with divalent metal salts (MnCl2, PbCl2 and CdCl2) in a mixed-solvent system, affording mononuclear to trinuclear structures namely, bis(methanol-κO)bis[5-(3-phenylprop-2-enamido)-1H-1,2,3,4-tetrazol-1-ido-κ2 N 1,O]manganese(II), [Mn(C10H8N5O)2(CH3OH)2], (1), bis[μ-5-(3-phenylprop-2-enamido)-1H-1,2,3,4-tetrazol-1-ido]-κ3 N 1,O:N 2;κ3 N 2:N 1,O-bis{aqua[5-(3-phenylprop-2-enamido)-1H-1,2,3,4-tetrazol-1-ido-κ2 N 1,O]lead(II)}, [Pb2(C10H8N5O)4(H2O)2], (2), and hexakis[μ2-5-(3-phenylprop-2-enamido)-1H-1,2,3,4-tetrazol-1-ido-κ3 N 1,O:N 2]tricadmium(II), [Cd3(C10H8N5O)6], (3). The structures of these three compounds reveal that the nature of the metal ions and the side groups of the organic building blocks have a significant effect on the structures of the coordination compounds formed. Intermolecular hydrogen bonds link the molecules into two-dimensional [complex (1)] and three-dimensional hydrogen-bonded networks. Complexes (2) and (3) show significant fluorescence, while complex (1) displays no fluorescence.
