Abstract

Binuclear metal complexes of the type [M(HDDB)-(H2O)2]2: where HDDB=1-hydroxy-2,3-dimethyl-4-(3prime-methyl-4prime-amino-5prime-mercapto-1prime, 2prime, 4prime-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.
