dc.description.abstract Şimdiye kadar bilinmeyen Schiff bazı-metal karbonil kompeksleri ışınlanma ara ürünü olan M(CO)5THF (M = Cr, Mo, W) ile dört Schiff baz ligandı N,N'-bis(2-aminotiyofenol)-1,4-bis(2-karboksaldehidfenoksibütan), N,N-bis(2-aminotiyofenol)-1,7-bis(2-formilfenil)-1,4,7-trioksaheptan, N,N'-bis(2-hidroksinaftalin-1-karbaldehiden)-1,2-bis(p-aminofenoksi)etan ve N,N-bis(2-hidroksinaftalin-1-karbaldehiden)-1,4-bis(p-aminofenoksi)bütan arasındaki fotokimyasal tepkime ile sentezlendi. Sentezlenen komplekslerin yapıları elementel analiz, LC- kütle spektrometrisi, manyetik çalışmalar, FTIR ve 1H NMR spektroskopisi ile aydınlatılmaya çalışıldı. Spektroskopik çalışmalar N,N'-bis(2-hidroksinaftalin-1-karbaldehiden)-1,2-bis(p-aminofenoksi)etan ve N,N'-bis(2-hidroksinaftalin-1-karbaldehiden)-1,4-bis(p-aminofenoksi)bütan ligandlarının merkez atomuna dört dişli ligandlar olarak koordine olmasına ek olarak N,N'-bis(2-aminotiyofenol)-1,4-bis(2-karboksaldehidfenoksibütan) ve N,N-bis(2-aminotiyofenol)-1,7-bis(2-formilfenil)-1,4,7-trioksaheptan ligandlarının UV ışınlanma sonrasında benzotiyazol türevlerine dönüştüğünü ve merkez atomuna köprü konumunda dört dişli ligandlar olarak bağlandığını göstermiştir. Anahtar sözcükler: N,N'-bis(2-aminotiyofenol)-1,4-bis(2-karboksaldehidfenoksibütan), N,N-bis(2-aminotiyofenol)-1,7-bis(2-formilfenil)-1,4,7-trioksaheptan, N,N'-bis(2-hidroksinaftalin-1-karbaldehiden)-1,2-bis(p-aminofenoksi)etan, N,N'-bis(2-hidroksinaftalin-1-karbaldehiden)-1,4-bis(p-aminofenoksi)bütan, metal karboniller, Schiff bazı. The hitherto unknown Schiff base-metal carbonyl complexes were synthesized by the photochemical reactions of photogenerated intermediate, M(CO)5THF (M = Cr, Mo, W) with four Schiff base ligands, N,N'-bis(2-aminothiophenol)-1,4-bis(2-carboxaldehydephenoxy)butane, N,N-bis(2-aminothiophenol)-1,7-bis(2-formylphenyl)-1,4,7-trioxaheptane, N,N'-bis(2-hydroxynaphthalin-1-carbaldehydene)-1,2-bis(p-aminophenoxy)ethane and N,N'-bis(2-hydroxynaphthalin-1-carbaldehydene)-1,4-bis(p-aminophenoxy)butane. The complexes were characterized by elemental analysis, LC- mass spectrometry, magnetic studies, FTIR and 1H NMR spectroscopy. The spectroscopic studies show that N,N'-bis(2-aminothiophenol)-1,4-bis(2-carboxaldehydephenoxy)butane and N,N-bis(2-aminothiophenol)-1,7-bis(2-formylphenyl)-1,4,7-trioxaheptane ligands are converted to benzothiazole derivatives after UV irradiation and coordinated to the central metal as bridging tetradentate ligands in addition to N,N'-bis(2-hydroxynaphthalin-1-carbaldehydene)-1,2-bis(p-aminophenoxy)ethane and N,N'-bis(2-hydroxynaphthalin-1-carbaldehydene)-1,4-bis(p-aminophenoxy)butane ligands are coordinated to the central metal as tetradentate ligands. Keywords: N,N'-bis(2-aminothiophenol)-1,4-bis(2-carboxaldehydephenoxy)butane, N,N-bis(2-aminothiophenol)-1,7-bis(2-formylphenyl)-1,4,7-trioxaheptane, N,N'-bis(2-hydroxynaphthalin-1-carbaldehydene)-1,2-bis(p-aminophenoxy)ethane, N,N'-bis(2-hydroxynaphthalin-1-carbaldehydene)-1,4-bis(p-aminophenoxy)butane, metal carbonyls, Schiff base. en_US
