The binuclear nitropyrazole compound [Re2O3Cl2(PPh3)2(C 3H2N3O2)2] (3) was synthesized by refluxing [ReOCl2(OEt) (PPh3)2] and 2-nitropyrazole in ethanol for 12 h. The octahedral {ReO2N2ClP} sites are linked by two bridging nitropyrazoles and an oxo group, with an Re-O-Re angle of 124.7(6)o. Compound 3 is electrochemically active, displaying a reversible one electron reduction at - 0.55 V with respect to Ag/Ag+. Crystal data: C36H34Cl2N6O7P 2Re2 (3), monoclinic C2/c, a = 32.569(7), b = 9.624(2), c = 29.151(6) A, β = 109.33(3)o, V = 8622(3) A3, Z = 8, Dcalc = 1.799 g cm-3, structure solution and refinement based on 3364 reflections converged at R = 0.056.
