“…Some of them or their metal complexes are used in various organic reaction processes as catalysts [3], models of reaction centers of metalloenzymes [4], have magnetic properties [5] and are nonlinear optical materials [6]. They can also be used as models for biomolecules and biological processes [7,8].…”

CCDC no.: 1482447The crystal structure is shown in the gure. Tables 1 and 2 contain details of the measurement method and a list of the atoms including atomic coordinates and displacement parameters. Source of materialTo an ethanol solution (5 mL) of 4-amino acetophenone ethoxy oxime (178.0 mg, 1 mmol) was added an ethanol solution (5 mL) of 3,5-dichlorosalicyde (279.9 mg, 1 mmol). After the solution had been stirred at 328 K for 10 h, the mixture was ltered, washed successively with ethanol and ethanol/hexane (1:4), respectively. The isolated compound was dried under reduced pressure and puri ed with recrystallization from ethanol solution to yield 300.7 mg of red

Source of materialToanethanol solution (5 ml) of 2 ¢ -hydroxyacetophenone (274.50 mg, 2.01 mmol) wasadded ane thanol solution (3 ml) of 1,4-bis-(aminooxy)butane (124.30 mg, 1.03 mmol). After the solution hadbeen stirred at55°Cfor 2h,the mixture wasfiltered. The residue wasw ashed successively with ethanol and ethanol/hexane (1:4),r espectively. The isolated compound wasd ried under reduced pressure and purified by recrystallization from ethanol to yield 119.10 mg of colorless crystallinesolid (yield 34 %, m.p. 132-133°C). The single crystals were obtained atRT by slow evaporationf rom amixture of tetrahydrofuran/methanol( 1:1, v / v ) and 2,2¢ -[(1,4-butylene)dioxybis(nitriloethylidyne)]-diphenol. DiscussionParticularattention hasr ecently been paid to the synthesis and study of salen and its derivatives. This is due to avarietyofreasons, not the least of which is theircrucialrole in inorganic and organometallic chemistry, e.g., they caneasily form metallosalen complexes with metalions asversatile chelating ligands. Some of them or their metalcomplexes are used in various organic reaction processes asc atalysts [1], models of reaction centers of metalloenzymes [2], have fascinating magnetic properties [3] and are nonlinearopticalmaterials [4]. They canalso be used asbiologicalm odels in understanding the structure of biomolecules and biologicalprocesses [5,6]. Most of their important features of these compounds are their preparative accessibility, diversityand structuralv ariability, which make them more attractive. Although the important properties of salen and its derivatives have been well-documented, it still seems there could be new and specific applications for such aunique group of compounds. The salen ligandsinmost of their metalcomplexes are stable insolution or solid state, however, the C = Nbonds often suffer exchange reaction asw ell ash ydrolysis. Because the oxime-type ligandsare more stable to resist the metathesis of C = Nbonds
