X-Ray Structures of Several Bis(N-alkylsalicylaldiminato)zinc(II) Complexes

چکیده
X-ray structures of five bis(N — R-salicylaldiminato)zinc(II) complexes with R — ethyl, «-propyl, /-propyl, «-butyl and 4-thia-rc-hexyl were determined. The N202 coordination geometry is in all cases gwas/-tetrahedral with the dihedral angle between the planes of the two chelate rings ranging from 84 to 89°. Bond lengths and angles in the coordination sphere are not affected by the nature of R or by a methoxy substituent in 4-position of the salicylaldimine. The potentially tridentate ONS ligand N(4-thia-rc-hexyl)salicylaldimine is also coordinated only in a bidentate NO fashion.
