Structure of the Dicyanophosphide Ion in a Crown‐Ether Sodium Salt

Abstract

Comparably large positively and negatively charged structural units are present in the lattice of the 1:1:1: complex of NaP(CN) 2 , [18]crown‐6, and tetrahydrofuran: Na + /crown ether/2 THF and Na + /crown ether/2P(CN) . The P(CN) ion is planar and bent; the calculated structure is essentially confirmed by X‐ray structure analysis. P/CN interaction is slight.
