Schiff bases are considered `versatile ligands' in coordination chemistry. The design of polynuclear complexes has become of interest due to their facile preparations and varied synthetic, structural and magnetic properties. The reaction of the `ligand complex' [CuL] {H2L is 2,2'-[propane-1,3-diylbis(nitrilomethanylylidene)]diphenol} with Ni(OAc)2·4H2O (OAc is acetate) in the presence of dicyanamide (dca) leads to the formation of bis(dicyanamido-1κN(1))bis(dimethyl sulfoxide)-2κO,3κO-bis{μ-2,2'-[propane-1,3-diylbis(nitrilomethanylylidene)]diphenolato}-1:2κ(6)O,O':O,N,N',O';1:3κ(6)O,O':O,N,N',O'-dicopper(II)nickel(II), [Cu2Ni(C17H16N2O2)2(C2N3)2(C2H6OS)2]. The complex shows strong absorption bands in the frequency region 2155-2269 cm(-1), which clearly proves the presence of terminal bonding dca groups. A single-crystal X-ray study revealed that two [CuL] units coordinate to an Ni(II) atom through the phenolate O atoms, with double phenolate bridges between Cu(II) and Ni(II) atoms. Two terminal dca groups complete the distorted octahedral geometry around the central Ni(II) atom. According to differential thermal analysis-thermogravimetric analysis (DTA-TGA), the title complex is stable up to 423 K and thermal decomposition starts with the release of two coordinated dimethyl sulfoxide molecules. Free H2L exhibits photoluminescence properties originating from intraligand (π-π*) transitions and fluorescence quenching is observed on complexation of H2L with Cu(II).

“…Kompleks 1'in soğurma bantları H2L ligand ile kıyaslandığında biri daha düşük diğeri ise daha yüksek dalga boylarına doğru kaymaktadır. Bu kaymaların sebebi, ligandın oksijen ve azot atomları ile bakır(II) iyonlarının koordinasyon yapmasıdır [37]. Kompleks 1'de görülen 440 nm'deki soğurma bandı ligandın, amin grubundaki π→π* elektronik geçişinden, 290 nm' deki soğurman bandı ise n→π* elektronik geçişinden kaynaklanmaktadır [37].…”

Özet: Polimerik bakır (II) komplekslerinin tasarımı ve sentezi, moleküler biyoloji, manyetizma ve fotolüminesans alanlarındaki potansiyel uygulamalarından dolayı büyük ilgi uyandırmaktadır. Bu çalışmada, fotolüminesans özellikler gösteren {Cu4O4} kübik formda, C38H40Cl4Cu4N4O10 (1) kompleksi rapor edilmektedir. Kompleks 1, solvotermal reaksiyon ile sentezlendi ve element analizi, FT-IR, katı UV-Vis spektroskopisi ve tek kristal X ışını kırınımı ile karakterize edildi. Kristal yapı çalışmaları, kompleks 1 in kristal yapısındaki dört çekirdekli birimdeki bakır(II) iyonlarının bozulmuş kare piramit geometriye sahip olduğunu gösterdi. Kompleks 1 ve ligandı H2L'nin katı durumdaki fotolüminesans özellikleri ise görünür bölgede oda sıcaklığında incelendi. Kompleks 1 ve ligandı H2L UV ışık ile 349 nm de uyarıldığı zaman, kompleks 1 görünür bölgede 452 nm'de şiddetli mor emisyon gösterirken, ligandı H2L 504 nm'de yeşil emisyon göstermektedir. Bu umut verici fotolüminesans davranış, bu tip bileşikler için duyarlı moleküler cihazlar veya organik ışık yayan diyotlar (OLEDs) için olası uygulamalara kapı açmaktadır. Investigation of Abstract:The design and synthesis of polymeric coordination copper(II) complexes are of great interest due to potential applications in the areas of molecular biology, magnetism and photoluminescence. In this study, reports the cubane-type {M4O4} complex of the formula C38H40Cl4Cu4N4O10 (1) showing photoluminescence properties. Complex 1 has been synthesised by the solvothermal reaction and characterized by element analysis, FT-IR, solid UV-Vis spectroscopy and single crystal X-ray diffraction. Crystal structural studies show that the Cu(II) centres in the tetrameric unit in complex 1 adopt distorted squarepyramidal geometries. The solid state photoluminescence properties of complex 1 and its ligand H2L have been investigated at room temperature in the visible region. When complex 1 and its ligand H2L are excited under UV light at 349 nm, complex 1 displays a strong violet emission at 452 nm and its ligand H2L displays green emission at 504 nm in the visible region. This promising luminescent behavior opens up possible applications for these compounds as sensing molecular devices or organic light emitting diodes (OLEDs).
