Abstract

The reactions of [HB(pz)₃ReOCl₂] (1) with chelating hydrazines were studied. In contrast to the common substitution pattern which occurs through a condensation type reaction to displace the oxo group in forming the metal-hydrazido functionality, 1 reacts with hydrazinophthalazine (hydralazine) to give [HB(pz)₃ReO(HNNC₈H₅N₂)] (2). Similarly, reaction with bishydrazinophthalazine produces the binuclear species [{HB(pz)₃ReO}₂{(HNN)₂C₈H₄N₂}] (3). The relative ease of substitution of the chloride groups in 1 is evident in the reactions of 1 with thiolate donors to yield complexes of the type [HB(pz)₃ReO(2-pyridinthiol)₂] (4). Crystal data: 2 · CH₂Cl₂, monoclinic P2₁/c, a = 12.820(3), b = 11.616(2), c = 15.626(3) A ̊, β = 104.93(3)°, V = 2248(1) A ̊³, Z = 4, D_calc = 1.171 g cm^-3; structure solution and refinement based on 2316 reflections converged at R = 0.0395. 4 · 1.5CH₂Cl₂, triclinic P1 ̄, a = 10.181(2), b = 14.159(3), c = 9.622(2) A ̊, α = 95.51(3), β = 93.25(3), γ = 88.18(3)°, V = 1377.9(7) A ̊³, Z = 2, D_calc = 1.718 g cm^-3; R = 0.0351 for 3291 reflections.
