  • Synthesis, characterisation and X-ray structural analysis of mu-di-nitrogen-bis[hydrotis(3,5-dimethylpyrazolyl)-borato-technetium- dicarbonyl], [L*Tc(CO)(2)](2)(mu-N(2))


The compound [HB(3,5-Me(2)C(3)N(2))(3)]Tc(CO)(3) reacts after UV irradiation in THF with elementary nitrogen to give the air-stable N(2)-bridged binuclear complex {[HB(3,5-Me(2)C(3)N(2))(3)]Tc(CO)(2)}(2)(mu-N(2)). The crystal and molecular structure of this first N(2)-bridged organometallic technetium complex has been determined by a single-crystal X-ray diffraction study. The compound crystallises in monoclinic form (space group C2/c) with cell parameters a = 2032.2(6), b = 1454.7(4) and c = 1427.0(5) pm, and Z = 4. The N-N distance is 116.0 pm and the Tc-N-N angle is 174.0 . The IR, 1H NMR, UV and EI-MS spectroscopic data are discussed.
