Mobilities of cation-macrocyclic ligand complexes
Formation constants for complexion between alkali metal cations and the crown ether 18C6 in the solvent 2-cyanopyridine at 3OoC were determined from conductance measurements. The method allows for precise determination of these formation constants up to values of K around 10" mol-' dm3. The method also f. permits accurate evaluation of association equilibrium constants between the complex speci...
متن کاملsynthesis of binuclear platinum complexes containing biphosphine ligand
هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
Synthesis and characterization of mono- and heterodinuclear complexes of dinucleating macrocyclic ligand bearing hexa- and pentadentate coordination sites
Macrocyclic heterobinuclear Zn(II)–Cu(II) complexes with phenol based dicompartmental ligands possessing contiguous hexa- and penta-coordination sites were prepared by a stepwise procedure. The ligands include similar N4O2 and dissimilar N(imine)3O2 and N(amine)3O2 coordination sites sharing two phenolic oxygen atoms. The six-coordination site comprises two pyridyl pendant arms on the amine nit...
متن کاملSynthesis and Characterization of Homo and Heterobimetallic Complexes with a Dicompartmental Macrocyclic Ligand Containing Propionitrile Pendent Arms
A binuclear macrocyclic ligand containing dissimilar N(amine)2O2 and N(imine)2O2 coordination sites sharing two phenolic oxygen atoms, was prepared by cyclic condensation of dialdehyde precursor L1H2 with 1,3-diaminopropane. The ligand includes two propionitrile pendant arms on the amine nitrogen atoms. The homobimetallic com...
متن کاملInternal Cation Mobilities in the Ternary Molten
With the Klemm method, ratios of internal mobilities in a ternary molten mixture (Li, Na, K)N0 3 of the eutectic composition (30-17-53 mol%) have been measured in the temperature range 473 K-673 K. The electric conductivity has been measured with a D. C. method. From these data the internal mobilities, bu, 6Na and bK, have been obtained on the assumption of additivity for the molar volume. In m...
