It's hip to be square : A perfectly planar square of phosphorus atoms is prepared by the reduction of [ZrCl 2 {PhP(CH 2 SiMe 2 NSiMe 2 CH 2 ) 2 PPh}] in the presence of P 4 (see structure). On the basis of the PP single bond lengths and oxidation state of the Zr centers, this unit is formulated as a [P 4 ] 4− fragment.
