Abstract

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 (LACHZ), N,N'-bis(2-hydroxyacetophenone)2,2'-dimethyl-1,3-propanediamine (LACDMH(2)) and N,N'bis(salicylidene)-1,2-ethylenediamine (SalenH(2)) were reduced in methanolic media with the help of NaBH4. Ni(H)-Sn(H) 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 mu-bridges. The Ni center dot center dot center dot Sn bridging distance is 3.1543(9) angstrom.
