“…The Ni II and Cu II atoms are bridged by two phenolate O atoms of an L ligand [Ni1-O1-Cu1 = 99.71 (7) and Ni1-O2-Cu1 = 102.86 (7) ]. These data are comparable with those of related complexes reported previously (Chen et al, 2014;Biswas et al, 2013;Yardan et al, 2014). The intramolecular NiÁ Á ÁCu distances are 3.063 (2) and 3.129 (2) Å , while the intra-molecular CuÁ Á ÁCu separation is 4.351 (2) Å .…”

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).

Novel ligand platforms that promote reactivity are of long standing and continued interest in coordination chemistry, with Schiff base ligands and their metal complexes representing one of the most versatile and long standing topics of interest. The synthesis and structure of polydentate Schiff bases and their metal complexes is fascinating, because it reveals a great richness of structural, physico-chemical and catalytic properties. Given the simplicity and ease of access to multidentate Schiff bases and their metal complexes, investigation of such compounds is essential to precise and understand structure-property relationships in order to optimize and improve their use in a wide range of fields, including catalysis, supramolecular chemistry, magnetism, electrochemistry, nanoscience, energy materials, and biological applications. This review highlights the recent developments of pentadentate, hexadentate, heptadentate and macrocyclic Schiff base ligands containing various donor sets made of different combinations of N, O, S or P donor atoms and their metal complexes (essentially mononuclear), as well as presenting synthetic methods and interesting structures of complexes formed by first-to-third row transition metals (from group 4-12), main group elements, lanthanides and actinides. This review is divided into three main sections, each of them corresponding to one type of denticity of the Schiff base under consideration. Each category is described with representative examples according to a periodic order, and emphasis is given to the coordination aspects. Their catalytic, magnetic and biological properties are also outlined. This review that contains 359 references should act as a source of information to researchers interested to work in this domain and stimulate further investigation in this fascinating area of Schiff base coordination compounds.

“…Our research group and others have successfully synthesized mononuclear, binuclear and tetranuclear copper(II) complexes (Hopa & Cokay, 2016a,b;Gungor & Kara, 2012, 2015Gungor et al, 2014;Celen et al, 2016;Yahsi, 2016;Yahsi & Kara, 2013;Yardan et al, 2014) and investigated their magnetostructural properties.

Binuclear and tetranuclear copper(II) complexes are of interest because of their structural, magnetic and photoluminescence properties. Of the several important configurations of tetranuclear copper(II) complexes, there are limited reports on the crystal structures and solid-state photoluminescence properties of `stepped' tetranuclear copper(II) complexes. A new Cu complex, namely bis{μ-3-[(4-methoxy-2-oxidobenzylidene)amino]propanolato}bis{μ-3-[(4-methoxy-2-oxidobenzylidene)amino]propanolato}tetracopper(II), [Cu(CHNO)], has been synthesized and characterized using elemental analysis, FT-IR, solid-state UV-Vis spectroscopy and single-crystal X-ray diffraction. The crystal structure determination shows that the complex is a stepped tetranuclear structure consisting of two dinuclear [Cu(L)] units {L is 3-[(4-methoxy-2-oxidobenzylidene)amino]propanolate}. The two terminal Cu atoms are four-coordinated in square-planar environments, while the two central Cu atoms are five-coordinated in square-pyramidal environments. The solid-state photoluminescence properties of both the complex and 3-[(2-hydroxy-4-methoxybenzylidene)amino]propanol (HL) have been investigated at room temperature in the visible region. When the complex and HL are excited under UV light at 349 nm, the complex displays a strong blue emission at 469 nm and HL displays a green emission at 515 nm.
