Zinc(II), ruthenium(II), rhodium(III), palladium(II), silver(I), platinum(II) and complexes of 2-(2′-hydroxy-5′-methylphenyl)-benzotriazole as simple or primary ligand and 2,2′-bipyridyl, 9,10-phenanthroline or triphenylphosphine as secondary ligands: Structure and anticancer activity

Preparation and spectroscopic studies of Fe(II), Ru(II), Pd(II) and Zn(II) complexes of Schiff base containing terephthalaldehyde and their transfer hydrogenation and Suzuki-Miyaura coupling reaction

“…And also, the other high-intensity bands in the 293-346 nm could be attributed to ( 1 A 1g → 1 T 2g ) and d→d transition, occurring within ligand orbitals. The electronic spectra was similar to that of Ru(II) octahedral complexes [46,47].…”

“…Zn(II)) complex was diamagnetic and had an octahedral geometry [45]. The structured absorption bands between 260 and 347-403 nm for Pd(II) complex were assigned to 1 A 1g → 1 B g and 1 A 1g → 1 E g transitions, respectively in a square-planar configuration [46]. And also, the other high-intensity bands in the 293-346 nm could be attributed to ( 1 A 1g → 1 T 2g ) and d→d transition, occurring within ligand orbitals.…”

Coordination compounds in cancer: Past, present and perspectives

“…Recently, it has been suggested that rhodium(III) complexes that are inert towards substitution may show low systemic toxicity (Geldmacher et al, 2012). Some interesting rhodium complexes are [Rh(2-(2 0 -hydroxy-5 0 -methylphenyl)-benzotriazole) 2 (H 2 O) 2 ]Cl that shows promising activity against human breast cancer (MDA-MB231) and human ovarian cancer (OVCAR-8) cell lines (El-Asmy et al, 2014) and also a series of rhodium(I)-N-heterocyclic carbene complexes with CO as secondary ligand, which shows marked antiproliferative effects together with moderate inhibitory activity of thioredoxin reductase and efficient binding to biomolecules (e.g., DNA, albumin). With the use of these complexes, modifications in the mitochondrial membrane potential and DNA fragmentation were observed in wild-type and daunorubicinor vincristine-resistant Nalm-6 leukaemia cell lines (Oehninger et al, 2013).…”

Removal of copper(II) ions from Aqueous Media by Chemically Modified MCM‐41 with N‐(3‐(trimethoxysilyl)propyl)ethylenediamine and Its 4‐hydroxysalicylidene Schiff‐base

“…Furthermore, the bands arise from azomethine m(C@N) and phenolic m(CAO) are shifted to lower wavenumbers [25,[51][52][53], indicating the introduction of the Cu(II) ions into MCM-41-N-Hdhba [25,[51][52][53][54]. The bands near 510, 450 cm 21 are attributed to m(CuAO) and m(CuAN), respectively [53,55]. Moreover, the copper content on MCM-41-NH 2 -Cu(II) and MCM-41-N-Hdhba-Cu(II) were found to be 2.7 and 3.4%, with N/Cu molar ratio 4:1 and 1:1, respectively, attributed to adsorption of Cu(II) ions onto sorbents.…”
