摘要
Four bis(salicylaldiminato)zinc(II) complexes have been synthesized from four Schiff bases obtained by the condensation of chiral (R)-(+)-1-phenylethylamine with salicylaldehyde (1), 5-nitrosalicylaldehyde (2), 3,5-dichlorosalicylaldehyde (3) and 5-methoxysalicylaidehyde (4). The complexes crystallize in the noncentrosymmetric space groups P2(1)2(1)2(1) (1), P2(1)(2). and C2 (3, 4). The geometry around the zinc(II) metal center is pseudo-tetrahedral with two oxygen and two nitrogen atoms from the ligands and has the A absolute configuration. Powders of the four compounds exhibit second harmonic generation (SHG) of intensity between that of 3-methyl-4-nitropyridine-1-oxide (POM) and N-(4-nitrophenyl)-(S)-prolinol (NPP).
