Keywords: Dimeric nickel-tin complex, Reduced Schiff base, Thermogravimetric analysis, Single crystal structure analysis, X-ray diffraction
N,N´-bis(salicylidene)-1,3-propanediamine (LH2), N,N´-bis(salicylidene)-2,2´- dimethyl-1,3-propane-diamine (LDMH2), N,N´-bis(2-hydroxyacetophenylidene)-1,3-propanediamine (LACH2), N,N´-bis(2-hydroxyacetophenone)-2,2´-dimethyl-1,3-propanediamine (LACDMH2) and N,N´-bis(salicylidene)-1,2-ethylenediamine (SalenH2) were reduced in methanolic media with the help of NaBH4. Ni(II)—Sn(II) heteronuclear complexes were synthesized according to the template method in DMF media. The complex structures were analyzed using elemental analysis, FTIR spectroscopy, thermogravimetry and X-ray diffraction. Appropriate crystals for one of the complexes 2 were obtained for X-ray diffraction. The Ni(II) ion has an octahedral coordination between the organic donors. The Sn(II) ion forms three membered coordination structure with phenolic oxygen atoms via μ-bridges. The Ni … Sn bridging distance is 3.1543(9) Ċ.
