New Pd-II complexes of biologically active ketimines containing the NO
H donor set have been synthesized and characterized by elemental analy
ses, molecular weight determinations and conductivity measurements. Th
e i.r. and H-1-n.m.r. spectra indicate a square planar structure for t
he complexes in which the ligand is monobasic bidentate with oxygen an
d azomethine nitrogen coordinating sites. Representative ketimines and
their respective metal complexes were found to exhibit antimicrobial
properties.
