Dört dişli Schiff baz sentezi ve Cu (II) ve Ni(II) komplekslerinin sentezi

The synthesis of fourdentate Schiff bases and their complexes with Cu(II) and Ni(II)

Özet

Değişik substutie diaminlerle (1,4-fenilendiamin, 4,4'-diaminodifenil, 4,4'-diaminodifenilmetan ve 4,4'-diaminodifenileter) salisilaldehit'in reaksiyonu sonucu dört dişli schiff bazları ( 1,4-fenilendiamin-bis-salisilaldehit, 1,1'-bifenil -4,4'diamino-bis-salisilaldehit, 1,1'-difenilmetan-4,4'-diamino-bis-salisilaldehit ve 1,1'-difeniloksi-4,4*-diamino-bis-salisilaldehit) elde edilmiştir. Elde edil'en bu değişik schiff bazların kare-düzlem yapılı polimerik Ni(ll) ve Cu(ll) kompleksleri elde edilerek elementel analiz, ÎR ve $^1 H$-NMR analiz çalışmaları ile yapıları aydınlatılmıştır.

Abstract

Salicylaldehyde has been condensed with diamines (1,4-phenylenediamine, 4,4'-diaminodiphenyl, 4,4'-diaminodiphenylmethane or 4,4'-diaminodiphenylether) to optain the tetradentate schiff's bases ( 1,4-phenylenediamine-bissalicylaldehyde, 1,1'-biphenyl 4,4'diamino-bis-salicylaldehide, 1,1'-diphenylmethane-4,4'-diamino-bis-salicyl-aldehyde, or 1,1'-diphenyloxy-4,4'-diamino-bis-salicylaldehyde. The polymeric Ni(ll) and Cu(ll) complexes of these schiff bases are square-planar. The structures of the above complexes were determined by $^1H$-NMR and IR Spectrocopy and elemental analyses.
