Nylon 6 is doped with iodine to form a complex. The doubly oriented specimen of the complex crystal is investigated by X-ray diffraction. The lattice constants of the complex crystal are determined; it has a monoclinic unit cell of the space group P21/a or P21 : a = 0.913 nm, b = 1.62 nm (chain axis), c = 1.79 nm and fl = 59.7 °. The hydrostatic compression of the crystal shows that the compressibility has become isotropic around the chain axis; doped iodines weaken the hydrogen bonds formed in the s-form of nylon 6. The structure of the complex crystal is discussed on the basis of the packing and orientation of polyiodine ions, I s and I[, in nylon 6.
