“…Especially derivatives of salicylaldehyde and diamine have been of greate interest. They act as tetra-dentate ligands and provide suitable coordination mode for transition metal ions, so that obtained complexes have great potential in catalysis and material chemistry [3].

Source of materialAll purchased chemicals were of reagent grade and used without further purification. N,N '-bis(2-hydroxyl-4-methoxysalicylidene)ethylenediamine (L) was prepared from the reaction of ethylenediamine and 2-hydroxy-4-methoxybezaldehyde in ethanol. Am ixture of ligand L( 0.328 g, 1m mol) and Ni(NO 3 ) 2 · 6H 2 O(0.29 g, 1mmol) in ethanol (15 ml) was refluxed for four hours under stirring. The progress of the reaction was monitored by TLC using hexane/ethylacetat (1/2, v/v)aseluent. The resultant mixture was filtered and the filtrate was kept at 4°Ctoevapo-rate slowly. The orange block-shaped single crystals suitable for X-ray crystal structure determination were obtained. Experimental detailsThe hydrogen atoms were included in the refinement at geometrically idealized positions with d(C-H) =0.95, 0.99 and 0.98 Å for aryl, methyl and methylene, respectively, and U iso (H) =1 .2 U eq (C). An absolute structure could not be established as the crystal was twinned and aTWIN command in conjunction with BASF (0.43) command was used to refine the structure. DiscussionDuring the last few decades, there has been considerable interest in the chemistry of Schiff base compounds. Schiff bases, containing different donor atoms, also find use in analytical applications for metal coordination [1,2]. Especially derivatives of salicylaldehyde and diamine have been of greate interest. They act as tetra-dentate ligands and provide suitable coordination mode for transition metal ions, so that obtained complexes have great potential in catalysis and material chemistry [3]. Nickel complexes with tetra-dentate Schiff base ligands have been wildly investigated and several oxidation states for nickel have been reported in such complexes [4][5][6]. Nickel can form mono and trinuclear complexes with tetradentate Schiff base ligands [6]. we investigated the synthesis and crystal structure of several Schiff bases derived amino-thiotriazin and thiotriazol and their Ag(I) and Cu(I) complexes [1,[7][8][9][10]. The nickel(II) is in the square planar environment formed by the tetra-dentate salen ligand. The phenoxy oxygen atoms O1, O2 and amine nitrogen atoms N1, N2 coordinate nickel (

A Schiff base ligand was synthesized from the reaction of isonicotinic acid hydrazide with 3-methoxysalicylaldehyde. The reaction of LH with Co(NO 3 ) 2 .6H 2 O in methanol gave dark red crystals of [Co(HL) 2 ](NO 3 ) 2 .3H 2 O and colorless crystals of the protonated ligand (HLH) C with nitrate as the counter ion, (HLH)(NO 3 ). In coordination to metal, Schiff base ligand was protonated via hetrocyclic nitrogen atom of the pyridine ring and deprotonated on the phenolic OH group, two ligands behave as neutral tridentate ligands. The extensive O-H¢¢¢O and N-H¢¢¢O hydrogen bonding interactions in the solid state contribute to the formation of an infinite one-dimensional chain in the complex.
