A bis(benzoxazole) ligand (HL) has been synthesized, and its reaction with Zn(OAc)2 has led to fluorescent complexes via formation of binuclear Zn(II)-Zn(ii) cores. The ligand-to-metal ratio of the complexes varies from 1:1 to 2:1, depending on the reaction conditions. A large binding constant K = 8.3 × 1020 [M-3] has been determined for the reaction L + Zn2+→L2:Zn22+. The result indicates that the bis(benzoxazole) ligand is a useful building block to construct a binuclear core. On the basis of X-ray analysis, the binuclear Zn(ii)-Zn(ii) distance in the complexes is determined to be ～3.22 A, which is quite comparable to that found in the enzymes (3.3 A). Absorption and fluorescence study shows that a subtle chemical environmental change within the binuclear core can induce a large optical response.
