## Abstract Adenosine (Ado) can accept three protons, at N1, N3, and N7, to give H~3~(Ado)^3+^, and thus has three macro acidity constants. Unfortunately, these constants do not reflect the real basicity of the N sites due to internal repulsions, for example, between (N1)H^+^ and (N7)H^+^. However,
In this note, we present the results of EPR and optical studies on the title compound. The EPR spectra are recorded from pure (non diluted) single crystals. The coalescence to a single line of the hyperfine structure is not observed here, the distance between the Cu++ ions being great enough to red
## Abstract Stepwise syntheses of monometallic palladium(II) and bimetallic palladium(II)/platinum(II) complexes were carried out in order to measure the metallophilicity of potential tetradentate bis(alkylthio)ylidenemalonato ligands. The reaction of [Pd](SO~4~) ([Pd] = (Me~4~en)Pd; Me~4~en = __N_
