Synthesis, reactivity and physico-chemical properties of novel chloro complex of nickel(II) containing benzoxazole ligand

New chloro complex of nickel(II) of the type [(mu-Cl)(2)Ni-2{eta(2)-(pbox)}(2)] (1) has been synthesized by the interaction of nickel(II) chloride with {2-(o-hydroxyphenyl))-benzoxazole (pboxH) in equimolar ratio (in refluxing EtOH). Further, it was treated with sodium salts of Schiff bases (sb) [sb...

Summary:New chloro complex of nickel(II) of the type [(mu-Cl)(2)Ni-2{eta(2)-(pbox)}(2)] (1) has been synthesized by the interaction of nickel(II) chloride with {2-(o-hydroxyphenyl))-benzoxazole (pboxH) in equimolar ratio (in refluxing EtOH). Further, it was treated with sodium salts of Schiff bases (sb) [sb = smabH and sapH], isopropoxide and aluminiumtetraisopropoxide and aryloxo- and alkoxo-salts in the presence of THF/pyridine to produce new hydrocarbon soluble mixed ligand complexes of the types : [(smab)Ni{eta(2)-(pbox})] (2), [(sap)Ni{eta(2)-(pbox)}] (3), [(mu-OPri)(2)Ni-2 {eta(2)-(pbox)}(2)] (4), [(mu-OAr)(2)Ni-2{eta(2-)(pbox)}(2)] (5) and [{(mu-OPri)(2)Al(OPri)(2)}Ni{eta(2)-(pbox)}] (6). These new products have been characterized by spectroscopic [IR, electronic (UV-visible), FAB-mass] and magnetic studies. A tentative T-d geometry around nickel(II) are proposed.
