Crystal Structure Of N,N,N ',N '-Tetrakis(Methyldiphenylphosphino)-Bis-(2 '-Phenoxy)-3,6-Dioxaoctane

Abstract

The title molecule, [C70H68N2O4P4], is a polydentate podand consisting of four etheral oxygens, two tertiary amine nitrogens and four diphenylphosphin groups. It crystallizes in the triclinic space group P (1) over bar, and there is only one half a molecule in the asymmetric unit. The coordinations around the N and P atoms are pyramidal. The conformations about C20-C21, O2-C21 and O2-C22 are gauche, anti and anti, respectively.
