Abstract
[Zr2Cl4(NPMe3)4(HNPMe3)] · CH3CN, a Phosphorane Iminato Complex with ZrN Double BondsThe title compound has been prepared from a molten mixture of ZrCl4 with Me3SiNPMe3 in the presence of potassium fluoride and subsequent extraction with acetonitrile. According to the crystal structure determination the zirconium atoms are linked by three μ2‐N atoms of two NPMe3− groups and by the HNPMe3 molecule. Two terminal bounded chlorine atoms and a terminally coordinated NPMe3− ligand complete the distorted octahedral surrounding of the zirconium atoms thus forming an edge sharing double octahedron. The ZrN bond lengths of the terminal NPMe3− groups of 194.6 pm correspond with double bonds.
