In conclusion, we have synthesised and characterised six new sawhorse-type complexes containing various carboxylato bridging ligands and the
approximately 7 days the formation of crystalline material 1 was occurred; a few selected single crystals were used for the X-ray diffraction analysis (see ESI for
A single crystal X-ray structure analysis of (3) [BF 4 ] confirmed the piano-stool geometry of 3 to be similar to that of 2 [8], however, due to low crystal quality, the structural
The single-crystal struc- ture analyses of 2, 3, 5 and 6 reveal a dinuclear Ru 2 (CO) 4 sawhorse structure, the diruthenium backbone being bridged by the car- boxylato ligands,
[17] No such hydrogen bonding has been ob- served in related palladium(II) complexes with C,N- or C,S- bidentate ligands comprising a phenyl instead of a pyr- idylidene as the
On the cyclic voltammogram, the first oxidation is electrochemically fully reversible, showing (when the switching potential is set before the second oxidation; see also below) the i
In both cases, the oxidation proceeds in two one-electron, narrow-spaced waves (RDE) or peaks (CV) followed by a third one; the potentials of the first process corresponding well
However, chiral carbon atoms in the carboxylic acid undergo racemisation during the thermal reaction.. Keywords: Carbonyl ligands; Carboxylato bridges; Biologically active
