Abstract

Reaction of [TcOCl4]- with hydralazine·HCl in methanol at room temperature yields the Tc(V)-hydrazido(3-) complex [Tc(C8H5N4)Cl2(PPh3)2]·0.75C8H7 (1). In contrast, the reaction in refluxing methylene chloride produces the Tc(V)-nitrido complex [TcNCl2(PPh3)2]·0.25CH2Cl2 (2). Crystal data. 1: triclinic P1, a=11.592(3), b=12.105(3), c=17.884(4) Å, α= 107.76(2)°, β=99.03(2)°, γ=106.11(2)°, V=2232.7(9) Å3, Z=2, Dcalc=1.40 g/m3; stucture solution and refinement based on 2623 reflections (F≥6σ(Fo); Mo Kα, λ=0.71073 Å) converged at R=0.058. 2: monoclinic C2/c, a=24.081(9), b=9.539(4), c=15.650(6) Å, β=116.18(1)° V=3226.8(11) Å3, Z=4, Dcalc=1.37 g/cm3; 3118 reflections; R=0.052.
