Abstract

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) Å, β = 109.33(3)^o, V = 8622(3) Å³, Z = 8, D_calc = 1.799 g cm^-3, structure solution and refinement based on 3364 reflections converged at R = 0.056.
