| Abstract: | Synthesis and Crystal Structure of the Selenyl-Phosphoraneiminato Complex SeO(NPPh3)2 SeO(NPPh3)2 has been prepared from SeO2 and Me3SiNPPh3 in a SeO2 suspension in acetonitrile, forming colourless crystals. The compound is characterized by IR spectroscopy and by a crystal structure determination. Space group P1 , Z = 2, structure solution with 5 344 observed unique reflections, R = 0.064. Lattice dimensions at ?40°C: a = 931.6, b = 947.6, c = 1 762 pm, α = 77.50°, β = 81.78°, γ = 79.23°. The compound forms monomeric molecules in which the selenium atom is φ-tetrahedrally surrounded with bond lengths SeO = 161.7 pm and SeN = 179.9 and 181.6 pm. |
