The dynamic behavior in solution of eight mono-hapto tetraphosphorus transition metal-complexes, trans-[Ru(dppm)2(H) (I·1-P4)]BF4 ([1]BF4), trans-[Ru(dppe)2(H)(I·1-P4)] BF4 ([2]BF4), [CpRu(PPh3) 2(I·1-P4)]PF6 ([3]PF6), [CpOs(PPh3)2(I· 1-P4)]PF6 ([4]PF6), [Cp*Ru(PPh3)2(I·1-P 4)]PF6 ([5]PF6), [Cp*Ru(dppe) (I·1-P4)]PF6 ([6]PF6), [Cp*Fe(dppe)(I·1-P4)]PF6 ([7]PF6), [(triphos)Re(CO)2(I·1- P4)]OTf ([8]OTf), and of three bimetallic Ru(mu, I·1:2-P4)Pt species [{Ru(dppm) 2(H)}(mu,I·1:2-P4){Pt(PPh 3)2}]BF4 ([1-Pt]BF4), [{Ru(dppe)2(H)}(mu,I·1:2-P 4){Pt(PPh3)2}]BF4 ([2-Pt]BF 4), [{CpRu(PPh3)2)}(mu,I· 1:2-P4){Pt(PPh3)2}]BF4 ([3-Pt]BF4), [dppm=bis(diphenylphosphanyl)methane; dppe=1,2-bis(diphenylphosphanyl)ethane; triphos=1,1,1- tris(diphenylphosphanylmethyl)ethane; Cp=I·5-C 5H5; Cp=I·5-C 5Me5] was studied by variable-temperature (VT) NMR and 31P{1H} exchange spectroscopy (EXSY). For most of the mononuclear species, NMR spectroscopy allowed to ascertain that the metal-coordinated P4 molecule experiences a dynamic process consisting, apart from the free rotation about the M-P4 axis, in a tumbling movement of the P4 cage while remaining chemically coordinated to the central metal. EXSY and VT 31P NMR experiments showed that also the binuclear complex cations [1-Pt]+-[3-Pt] + are subjected to molecular motions featured by the shift of each metal from one P to an adjacent one of the P4 moiety. The relative mobility of the metal fragments (Ru vs. Pt) was found to depend on the co-ligands of the binuclear complexes. For complexes [2]BF4 and [3]PF6, MAS, 31P NMR experiments revealed that the dynamic processes observed in solution (i.e., rotation and tumbling) may take place also in the solid state. The activation parameters for the dynamic processes of complexes 1+, 2+, 3+, 4+, 6 +, 8+ in solution, as well as the X-ray structures of 2+, 3+, 5+, 6+ are also reported. The data collected suggest that metal-coordinated P4 should not be considered as a static ligand in solution and in the solid state. A detailed solution and solid-state NMR dynamics study on mono- and bimetallic transition metal complexes, coordinating white phosphorus in I·1- P4 fashion, has revealed that this ligand is endowed of motions which depend on the nature of co-ligands and geometries around the metals. Activation parameters of the processes and X-ray crystal structures were also obtained (see figure). Copyright

The effect of protonation on the spectroscopic properties of Re(I) and Ru(II) complexes with the ligand 11-triphenylamine-dipyrido[3,2-a:2?,3?-c]phenazine (dppz-TAA) are investigated. For [Re(CO)3Cl (dppz-TAA)] protonation with triflic acid in CH2Cl2 results in a depletion of the intraligand charge-transfer transition at 500 nm (epsilon = 17700 M-1 cm-1) and the concomitant grow-in of a band at 780 nm (epsilon = 18200 L mol-1 cm-1). Resonance Raman spectra of the protonated species show a strong band at 1628 cm-1 attributed, through DFT modeling, to a TAA mode with bending of the phenazine NH linkage. The low energy band is also predicted by TD DFT. The behavior of [Ru(bpy)2(dppz-TAA)]Cl2 was studied in aqueous solution as a function of pH. The electronic absorption spectrum shows modest changes as a function of pH. The excited state properties show a short-lived emissive state (lambdamax = 500 nm) that is diminished in intensity at lower pH. The compound also has a long-lived dark state with absorption features at 420 and 700 nm; the lifetime of this state is also pH sensitive varying from 2500 to 500 ns. The dark long-lived state is probed with transient resonance Raman spectroscopy and is assigned as a 3pi; pi? ligand state. This is consistent with DFT studies. From these data the pKa for [Ru(bpy)2(dppz-TAA)]Cl2 is estimated as 4.5.

The EPR spectra of CsMgCl3 crystals doped with Gd(III) and Ru(III) contain the resonances from a magnetically coupled Gd(III)-Ru(III) pair.The pair spectrum exhibits the fine structure characteristic of a Gd(III) ion (S=7/2) in an axial lattice site.At 77 K the weak coupling with the Ru(III) ion (S=1/2) splits each resonance into a doublet.The spectrum is well enough resolved to allow a characterization as a function of crystal orientation.A spin Hamiltonian which assumes a simple anisotropic interaction between the two ions is adequate to describe the spectrum (Etap=JzSzSz’+Jxy(SySx’+SySy’); where =+0.0055 cm-1 and =0.020 cm-1).The analysis determines that the principal g values of Gd(III) and Ru(III) have opposite sign (for Gd(III): gz=+1.991 and =1.991; for Ru(III): gz’=-2.35 and =1.62).The magnetic properties of the Gd(III)-Ru(III) dimer are discussed.As a part of this analysis, the spectra of a number of monomeric centers containing Gd(III) and Ru(III) were characterized.The properties of these centers are also discussed.
