Abstract:
N-substituted pyridino-based congeners of Ebselen, named here as Pyrselen, incorporating proximal Se and N atoms, undergo dimerization in solution and the solid state through a dual donor-acceptor arrangement of chalcogen bonding sites. Dimerization constants were measured within the 5-50 M-1 range. Computational studies on the dimers depict a notable charge-transfer contribution to the association, validating Pyrselen as an effective scaffold for designing chalcogen-bonding-based recognition motifs.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
