Three new ionic salts containing [M(CN)8]4? (M = MoIV and WIV) were prepared using large complex cations based on a non-conventional motif built with the tris(2-aminoethyl)amine (noted hereafter tren) ligand, [{M’(tren)}3(?-tren)]6+ (M’ CuII ZnII). The crystal structures of three compounds show that atomic arrangement is formed by relatively isolated anionic cationic entities. irradiated blue l...
A partial least-squares multivariate calibration method for the resolution of mixtures of metal ions from the spectra of the complexes produced in a flow injection (FI) system has been developed. The method has been applied to the simultaneous determination of Cull and Znii with 4-(4'-methyl-2'-thiazolylazo)-2-methylresorcinol. The reagent exhibits a high absorbance and its spectrum strongly ov...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
We present a straightforward and generally applicable synthesis route for cofacially linked homo- heterobimetallic porphyrin complexes. The protocol allows the of unsymmetrical aryl-based meso-meso as well β-meso-linked porphyrins. Our method significantly increases overall yield published compound known o-phenylene-bisporphyrin (OBBP) by factor 6.8. Besides 16 novel homobimetallic complexes co...
We report on the synthesis and crystal structure of solvent-free coordination polymer CoII(2,5-DMT) (1) with 2,5-DMT ≡ 2,5-dimethoxyterephthalate which is isostructural to already reported MnII ZnII congeners (C2/c, Z = 4). In contrast, for M MgII, a MOF DMF-filled pores obtained, namely Mg2(2,5-DMT)2(DMF)2 (2) (P1¯, 2). Attempts remove these solvent molecules record gas sorption isotherm did n...
A new oxy(ether)tris(amine) macrocycle, MC has been synthesized for CuII complex formation within the cavity of the macrocyclic wheel in endotopic fashion. This complex is further reacted with the bidentate chelating ligands, 1,10-phenanthroline (L1), 2,2′-bipyridyl (L2), 4,4′-dimethyl-2,2′-bipyridyl (L3) and 5,5′-dimethyl-2,2′-bipyridyl (L4) to achieve the pseudorotaxanes PRT1–PRT4, respective...
