Crystal structure of bis[4-chloro-2-(m-tolyliminomethyl)-phenolato]copper(II), Cu(C14H11NOCl)2

C28H22Cl2CuN2O2 ,m onoclinic, P121/c 1( no. 14), a =9 .881(1) A, b =1 1.049(1) A, c =1 1.913(1) A, * =1 04.903(1)°, V =1 256.9 A 3 , Z =2 , Rgt(F) =0 .046, wRref(F 2 ) =0 .142, T =2 98 K. Source of material 5-Chlorosalicylaldehyde (0.2 mmol, 31.31 mg), and m-toluidine (0.2 mmol, 21.4 mg) were dissolved in methanol (10 mL). After stirring for about 30 min, this solution was added slowly into the solution of CuCl2 · 2H2 O( 34.0 mg, 0.2 mmol) in 10 mL methnol. The resulting clear solution was kept at room temperature for about seven days, obtaining brown block-shaped crystals. The crystals were collected, washed with small amounts of methanol, and finally dried in vacuum (yield 58.4 %). Discussion
