Abstract

The fluorescent dye syn-(Me,Me)bimane interacts with the biorelevant Na⁺ ion to form labile complexes, three of which were crystallographically characterized, exhibiting new modes of bimane coordination. In water, as well as in organic solvents, Na⁺ complexation induces the quenching of bimane fluorescence.
