[Zr 2 Cl 4 (NPMe 3 ) 4 (HNPMe 3 )] · CH 3 CN, a Phosphorane Iminato Complex with ZrN Double Bonds The title compound has been prepared from a molten mixture of ZrCl 4 with Me 3 SiNPMe 3 in the presence of potassium fluoride and subsequent extraction with acetonitrile. According to the crystal structure determination the zirconium atoms are linked by three μ 2 ‐N atoms of two NPMe 3 − groups and by the HNPMe 3 molecule. Two terminal bounded chlorine atoms and a terminally coordinated NPMe 3 − ligand complete the distorted octahedral surrounding of the zirconium atoms thus forming an edge sharing double octahedron. The ZrN bond lengths of the terminal NPMe 3 − groups of 194.6 pm correspond with double bonds.
