Summary Binuclear metal complexes of the type [M(HDDB)-(H2O)2]2: where HDDB=1-hydroxy-2,3-dimethyl-4-(3-methyl-4-amino-5-mercapto-1, 2, 4-triazole)-1,4-diaza-1, 3-butadiene and M=manganese(II), cobalt(II), nickel(II) and copper(II), have been prepared and characterised by elemental and thermal analyses, magnetic measurements, electronic and i.r. spectra. Octahedral geometry around the metal(II) ions is proposed and the crystal field parameters of the cobalt(II) and nickel(II) complexes are also calculated. Fungicidal screening of the complexes has been made aginstHelminthosporium oryzae andFusarium oxysporium. 相似文献

Summary Binuclear complexes of the type [M(HDCDP)(H2O)n]2 and [M(HDCDB)(H2O)n]2, where HDCDP and HDCDB are Schiff bases derived from glycine and diacetylmonoxime, and orthoaminobenzoic acid and diacetylmonoxime respectively, M=VOII, CoII, NiII, CuII or AgII and n=0 or 2, have been synthesized. Physical and spectroscopic analyses indicate a binuclear structure for the complexes with metal ions in an octahedral environment, where the ligands coordinate to the metal centre through azomethine nitrogens, oxime and carboxylate oxygen in a tetradentate manner. 相似文献
