Abstract

Abstract Nickel (II) complexes of the type Ni[Ag(SCN)2]2.L [where L = benzoic acid hydrazide (BH), salicylic acid hydrazide (SH), anthranilic acid hydrazide (AH), isonicotinic acid hydrazide (INH), oxaldihydrazide (ODH), malondihydrazide (MDH) and their isopropanone derivatives, viz., isopropanone benzoyl hydrazone (IBH),-salicyl-hydrazone (ISH), -anthranoylhydrazone (IAH) and -isonicotinoyl hydrazone (IINH)] were synthesised and characterized with the help of elemental analyses, electronic, IR and magnetic moment data. The complexes are insoluble in common organic solvents, partially dissociate or dissolve in DMF and DMSO, have coordinated hydrazide or hydrazone ligands and bridging SCN groups. Nickel (II) in the complexes is spin free and has a pseudo-octahedral environment.
