The 1H NMR spectrum of [Ru(Lth) 3](PF 6) 2 showed that the expected 11 1:3 fac : mer ratio of geometric isomers has formed. In the threefold-symmetric fac isomer all three ligands are equivalent Weller & Young: Characterisation Methods in Inorganic Chemistry 4.4. 4.4 The carbonylation of RuCl 3 using a mixture of HCl and HCOOH followed by precipitation with CsCl gave complexes Cs 2 [Ru(CO) 2 Cl 4] A after four hours and Cs[Ru(CO) 3 Cl 3] B after twenty hours. A series of facial fac-[Ir(5-R-bzq)3] and meridional mer-[Ir(5-R-bzq)3] Ir(III) complexes bearing benzo[h]quinoline-based ligands have been studied with the help of density functional theory (DFT) methods. A detailed electronic structure comparison of the two isomers has been addressed to point out the differences in their stability and photophysical properties. An influence of substituent Irradiation of the optically resolved mer-Δ isomer of tris(1-phenylpyrazolato,N,C2′)iridium(III) with 366-nm light in CH3CN purged by argon at 25 °C gave 59 % fac-Δ and 41 % fac-Λ (18 % ee The Synthesis and X-ray Structural Characterization of mer and fac isomers of the Technetium(I) Nitrosyl Complex [TcCl(2)(NO)(PNPpr) August 2009 Inorganica Chimica Acta 362(10):3637-3640 For example, both the mer and fac isomers of the cyclometallated iridium(III) complexes, bearing ligands derived from the parent 2-phenylpyridine are easily accessible.20­23 These are generally isolated initially as the kinetically favoured mer isomer, which can then be converted to the fac isomer on heating presumably as a result of an The 1H NMR spectrum of [Ru(Lth)3](PF6)2 showed that the expected11 1:3 fac : mer ratio of geometric isomers has formed. In the threefold-symmetric fac isomer   Fac/Mer isomers arise when there are two equal types of ligand in an octahedral metal complex.

The mer isomer is also known as meridional isomer or trans isomer. powder (mer and/or fac isomers) and gives useful details about the structure of the Alq3 in order to indentify each isomer contribution. In the figure 3, it is a comparison between the Raman behaviors of the pale yellowish powder obtained by solid state reaction, the mer-Alq3 compound and the 8-hydroxyquinoline.

2013-02-25 · The fac isomer with three L-M-CO groupings is therefore favored over the mer arrangement (two L-M-CO groupings). Steric argument: PR3 ligands have a huge difference in size (Tolman cone angle) and for large PR3 ligands the mer arrangement (two PR3..R3P interactions) is preferred over the fac isomer (three PR3..R3P interactions).

Abstract The investigation involved reacting benzylamine with 2-pyridine carboxaldehyde with addition of iron (II) tetrafluoroborate producing a low spin octahedral complex displaying fac/mer isomerism.

In a fac isomer, any two identical ligands are adjacent or cis to each other. If these three ligands and the metal ion are in one plane, the isomer is said to be meridional, or mer. A mer isomer can be considered as a combination of a trans and a cis, since it contains both trans and cis pairs of identical ligands.
