Synthesis, structure and antifungal activity of thiophene-2,3-dicarboxaldehyde bis(thiosemicarbazone) and nickel(II), copper(II) and cadmium(II) complexes: Unsymmetrical coordination mode of nickel complex

Nickel-diflunisal complexes: synthesis, characterization, in vitro antioxidant activity and interaction with DNA and albumins

“…contact dermatitis) which may be shown by individuals bearing nickel-coated jewellery [23,24]. More bioinorganic chemists were interested to the nickel compounds and reported the biological activity of Ni(II) complexes bearing vitamins [25], antitumor antibiotics [26], anticonvulsant [27] or antiepileptic agents [28] as ligands; within this context, nickel(II) complexes have been reported in regard to their pronounced antibacterial [29,30], antifungal [30,31], antiinflammatory/antioxidant [32][33][34], antileishmanian [35] and antiproliferative activity towards diverse cell lines [36,37] and their interaction with DNA as intercalating [38,39] or cleaving agents [40,41]. In regard to the nickel complexes with NSAIDs as ligands reported in the literature, a series of Ni(II)-diclofenac (one structure) [42] and Ni-mefenamato (four structures) [43] complexes have been prepared, characterized and their interaction with biomolecules was in vitro studied.…”

Anomalous coordination behaviour of 6‐methyl‐2‐oxo‐1,2‐dihydroquinoline‐3‐carboxaldehyde‐4(N)‐substituted Schiff bases in Cu(II) complexes: Studies of structure, biomolecular interactions and cytotoxicity

“…Conversely, the bands at 360–361 nm were assigned to n → л* transition of the nitrogen lone pairs to the aromatic ring. The two bands were observed to bathochromically shift upon coordination of Schiff bases to the copper metal centre as a result of extensive conjugation of л‐electrons in the compounds . The absorption spectra of complexes 1 – 4 exhibited three bands in the region 219–408 nm.…”

NLO Properties of Unidirectional Lengthening [Pt3(CO)3(μ2-CO)3] n 2− Clusters: A TDDFT Study

“…The geometry structure of the hexa-platinum carbonyl cluster dianion [Pt 3 (CO) 3 (l2-CO) 3 ] 2 2-(II) [5] contains two parallel triangular platinum carbonyl plane layers, and is in crystallographic C 2-2 site symmetry, which would conforms to D 3h-62 hexagonal symmetry if in ideal condition with the six platinum atoms arranged in a trigonalprismatic array. However, Fig.…”

“…In recent years, many efforts have been devoted to searching multifunctional materials in the area of transition metal (TM) coordination complexes for their characteristics, including their multiform structures, various oxidation states and biological chemistry [1], unique roles which they play in heterogeneous catalysis [2,3] and optical and magnetic applications [4].…”
