Highly luminescent charge-neutral europium(iii) and terbium(iii) complexes with tridentate nitrogen ligands.
We report on the synthesis of tridentate-nitrogen pyrazole-pyridine-tetrazole (L(1)H) and pyrazole-pyridine-triazole (L(2)H) ligands and their complexation with lanthanides (Ln = Gd(iii), Eu(iii) and Tb(iii)) resulting in stable, charge-neutral complexes Ln(L(1))3 and Ln(L(2))3, respectively. X-ray crystallographic analysis of the complexes with L(1) ligands revealed tricapped trigonal coordina...
متن کاملNiobium tetrahalide complexes with neutral diphosphine ligands.
The reactions of NbCl4 with diphosphine ligands o-C6H4(PMe2)2, Me2PCH2CH2PMe2 or Et2PCH2CH2PEt2 in a 1 : 2 molar ratio in MeCN solution produced eight-coordinate [NbCl4(diphosphine)2]. [NbBr4(diphosphine)2] (diphosphine = o-C6H4(PMe2)2 or Me2PCH2CH2PMe2) were made similarly from NbBr4. X-ray crystal structures show that [NbCl4{o-C6H4(PMe2)2}2] has a dodecahedral geometry, but the complexes with...
متن کاملSynthesis of chelating bidentate and tridentate cyano ligands and their complexes with Group VII metal carbonyls
Two new bidentate cyano ligands, DiCN-3 (2) and DEN-4 (3) (a,w-bis(2-cyanophenoxy)propane and butane, respectively), have been prepared. These ligands and the ethane analogue DEN-2 (1) react with Mn(C0)5Br to afford complexes of the composition Mr~(cO)~(DicN-n)Br (n= 2, 9; n = 3, 10; n = 4, 11). Complexes 9 and 10 appear to be mononuclear and contain 13and 14-membered chelate rings, respectivel...
متن کاملMononuclear iron(iii) complexes of tridentate ligands with efficient nuclease activity and studies of their cytotoxicity.
Mononuclear mono- and bis-chelated iron(iii) complexes [Fe(Phimp)(H2O)(OMe)Cl], 1, [Fe(Phimp)Cl2], 2, [Fe(Me-Phimp)Cl2], 3, [Fe(N-Phimp)Cl2], 4, [Fe(Phimp)2](ClO4), 5, [Fe(Me-Phimp)2](NO3)·H2O, 6·H2O, and [Fe(N-Phimp)2](ClO4), 7, derived from tridentate ligands, have been synthesised and characterized. The X-ray crystal structures of the complexes 2, 4, 5 and 6·H2O were determined. The high-spi...
متن کاملSynthesis and crystal structures of ethanol-coordinated molybdenum(VI) oxo complexes with tridentate hydrazone ligands.
Reaction of [MoO2(acac)2] (where acac = acetylacetonate) with two similar hydrazone ligands in ethanol yielded two ethanol-coordinated mononuclear molybdenum(VI) oxo complexes with general formula [MoO2L(EtOH)], where L = L1 = (N'-(3,5-dibromo-2-hydroxybenzylidene)-4-nitrobenzohydrazide (H2L1), and L = L2 = (N'-(3,5-dibromo-2-hydroxybenzylidene)-2-fluorobenzohydrazide (H2L2). Crystal and molecu...
