Abstract

V. P. Singh and Jyoti Singh

 M [Tl(SCN) ₂]₂  type of complexes with Co(ll), Ni(Il). (Where as M = Co(ll), Ni(ll). L = Oxai di hyorazide (ODH), Phthalyl di hydrazide (PDH). Disaiicylaldimmeoxamide (H A) Disalicylaidimineophthalamide (H₄ B). Salicylalhydrazone (SH). They are either coordinated through C=C and -NH₂ groups of the hydrazines or C=0 and C=N of hydrazone ligands .The electronic and IR spectra suggest that in nickel (II) complexes shows pseudo octaheoral environment around Ni(ll) and Co(ll) complexes show tetragonally distorted octahedral environment around Co (II).

Hyorazide; Disalicylaidimineophthalamide; Salicylalhydrazone
