The complexation behaviour of 2,2Ј-bipyridyl-3,3Ј-diol and 2,2Ј-bipyridyl-3-ol, BP(OH) 2 and BPOH, with various heavy and transition metal ions has been investigated in aqueous, alcoholic, and acetonitrile solutions. Whereas the complexes with paramagnetic ions and Hg II are non-fluorescent, Zn II a

## Abstract __Density functional theory and quantum dynamics simulations have been used to study the double‐proton transfer reaction in 2,2′‐bipyridyl‐3,3′‐diol in the first singlet excited electronic state. This process is experimentally known to be branched: It consists of a fast, concerted react
## Abstract A classical model of “molecular machine,” which acts as an ON–OFF switch for 2,2′‐bipyridyl‐3,3′‐15‐crown‐5 (**L**), has been theoretically studied. It is highly important to understand the mechanism of this switch. The alkali‐metal cations (Na^+^ and K^+^) and W(CO)~4~ fragment are int
## Abstract By the use of the INEPT pulse sequence it has been possible to obtain ^15^N and ^103^Rh NMR data on [RhH~2~(PPh~3~)~2~(bipy)]Cl (bipy = 2,2′‐bipyridyl) containing natural abundance ^15^N and prove the stereochemistry; ^1^H and ^31^P NMR data are also reported for [RhH~2~(PPh~3~)~2~(bipy
