Abstract
The polycrystalline powder of the cyclic tetramer ester based on bisph enol-A and o-phthaloyldichloride has been prepared by recrystallizatio n from nitrobenzene and its crystal structure determined by wide-angle X-ray diffraction. The unit cell is orthorhombic and has dimensions a =0.967 nm, b=0.8699 nm, c = 2.0859 nm. With two tetramers per unit cel l, the crystal density is 1.36 g cm(-3). Indices of crystal diffractio n peaks are also detailed in the present work. Copyright (C) 1996 Else vier Science Ltd.
