“…On the other hand, a wide variety of Zn(II) complexes containing (E)-N-(pyridin-2-ylmethylene)arylamine (L R ) have been synthesized and their structures have been determined, for example [Zn(I) 2 (L H )], 16 [Zn(Br) 2 (L 4-I )], 17 [Zn(Cl) 2 (L 4-I )], 18 [Zn(I) 2 (L 4-Br )], 19 [Zn(I) 2 (L 2,5-Me2 )], 20 [Zn(Cl) 2 (L H )], 21,22 [Zn(Cl) 2 -(L 4-NMe2 )], 22 [Zn(Br) 2 (L 4-NO2 )], 23 [Zn(I) 2 (L 4-OMe )], 24 [Zn(Br) 2 -(L 4-F )], 25 [Zn(Br) 2 (L H )], 26 [Zn(Cl) 2 (L 2-Me )], 26 [Zn(Cl) 2 (L 4-Me )], 26 [Zn(Cl) 2 (L 4-CO2Me )], 26 [Zn(Br) 2 (L 4-CO2Me )], 26 [Zn(I) 2 (L 4-CO2Me )], 26 [Zn(Cl) 2 (L 2-OMe )] 26 and [Zn(μ-N 3 )(N 3 )(L 4-Me )] 2 . 26 In all the complexes, the zinc centre displays a moderately distorted tetrahedral coordination geometry defined by two halide anions and two N atoms of the ligand L R , except for the last two complexes.…”
