A series of binuclear Schiff-base complexes of zinc(II) and mercury(II) containing bidentate ligands (HL) [HL = salicylidene-2-methyl-1-aminobenzene (HL1), salicylidene-2-aminopyridine (HL2), and salicylidene-3-nitro-1-aminobenzene (

experimental part, p. 1605 - 1612 (2012/04/23)
A complex [(μ-Cl)2Cu2{η2-(pbox)} 2] (1) has been isolated by the reaction of copper(II) chloride (hydrated) with {2-(o-hydroxyphenyi)}benzoxazole (pboxH) in equimolar ratio [in ethanolic medium] and was found to be insoluble in most of the organic solvents; resulting product was treated with sodium salts of various Schiff bases, isopropoxide and aluminium tetraisopropoxide in presence of THF/pyridine produced the complexes of the type [(smab)Cu{η2-(pbox)] (2), [(sap)Cu{η2-(pbox)}] (3) and [(opr1) 2Cu2{n2-(pbox)}2] (4), [{Al(opr 1)4}Cu{η2-(pbox)}] (5). These products have been characterized by elemental analysis (C, H, N), Volhard's method (for Cl) and AAS (for Cu), melting points, spectroscopic (IR, UV-Visible, ESR, FAB-MS) and magnetic studies.

body text, p. 387 - 394 (2009/07/18)
New chloro complex of nickel(II) of the type [(μ-Cl)2Ni 2{η2-(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{η2-(pbox)}] (2), [(sap)Ni{η2- (pbox)}] (3), [(μ-OPri)2Ni2{η 2-(pbox)}2] (4), [(μ-OAr)2Ni 2{η2-(pbox)}2] (5) and [{μ-OPr i)2Al(OPri)2}Ni{η2- (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.
