A polynuclear d10-d10 metal complex with unusual near-infrared luminescence and high thermal stability.
Three d(10)-d(10) transition-metal complexes with organosulfur ligands, Cu(6)(btt)(6) (1), Cu(4)(btt)(4) (2), and Ag(6)(bmt)(6) x 6 THF (3) (Hbtt = 2-benzothiazolethiol, Hbmt = 2-benzimidazolethiol, and THF = tetrahydrofuran), were synthesized and characterized. Complexes 1 and 2 with similar coordination environments are isomers crystallized from the same solvothermal reactions, but they cause great differences in both the structures and luminescent behaviors. The hexanuclear cluster 1 exhibits unusual near-infrared luminescence and high thermal stability, while complex 2 with tetranuclear cores and stronger metal-metal bonds shows an intense red emission like that from complex 3.
