## Abstract The crystal structure of poly(aryl ether biphenyl ether ketone ketone) (PEDEKK) was determined to comprise a twoβchain orthorhombic unit cell with dimensions __a__ = 0.778 nm, __b__ = 0.606 nm and __c__ = 2.375 nm by using wideβangle Xβray diffraction (WAXD). According to the orthorhomb

A new crystal modification induced by strain and denoted as form II exists alongside the dominant form I structure in the uniaxially oriented poly(ether ether ketone) (PEEK) and the related polymers. The crystal structure of form II for PEEK is also found to possess a two-chain orthorhombic packing
Non-bonded potentials for the aryl..aryl interaction have been derived using crystal structure data of a number of small aromatic molecules. The potentials, based on atom-centred interactions, give an accurate reproduction of the benzene crystal geometry and sublimation energy when used in conjuncti
