Abstract: | Trans-methyl-azido-bis(triisopropylphosphine)platinum(II), [PtN3(CH3)(PiPr3)2] [PtN3(CH3)(PiPr3)2] has been prepared by reductive elimination of ethane from [Pt(CH3)3N3]4 in the presence of triisopropylphosphine at 80 °C. The complex is characterized by IR and NMR spectroscopy and by crystal structure determination, as well as by ab initio calculations. [PtN3(CH3)(PiPr3)2], which is in trans-configuration here, crystallizes in the monoclinic space group P21, Z = 2, and with the lattice dimensions a = 806.9(1), b = 1384.3(1), c = 1093.8(1) pm, β = 94.107(10)°. |
