A dinuclear oxo-Mo(V) complex 1 has been prepared which develops an intense absorption in the near-IR region (λ = 1340 nm; ε = 23 000 M-1 cm-1 on reversible one-electron oxidation to [1]+. This has formed the basis of a variable optical attenuator, whereby the intensity of near-IR laser light may be modulated over a range of 50 dB according to the electrical potential applied to the cell.
