Crystal structure of a new homo trinuclear Ni(II) complex with μ-cyanoacetato bridge

摘要: Ni(II)-Ni(II)-Ni(II) homo-trinuclear linear complex was prepared using bis-N,N'(2-hydroxybenzyl)-1,3-propanediamine in DMF (dimethyl formamide) medium. μ-bridges between metal nuclei are formed formate, acetate, chloroacetate and benzoate ions. The structure of the determined with X-ray diffraction method. It found that terminal Ni(II) ions have a N 2 O 4 coordination sphere central ion has 6 octahedral sphere. chelate ring, by Ni atoms aminic nitrogen atoms, to chair conformation. complexes were elucidated use thermogravimetry differential thermal analysis In chloroacetate, cyanoacetate containing dissociation took place first while formate it observed bridges degraded together moiety. stability carboxylate μ-bridge affects homo-nuclear complex. average bond energies coordinated molecules these coordinative be dimension hydrogen bonds.
