Abstract
X-ray studies have been carried out on magnetically aligned samples of nematic bis[1-(p-n-decylbiphenyl)3-(p-ethoxyphenyl) propane-1, 3-dionato] copper(II). The diffraction pattern consists of three diffuse maxima as would be expected from an orthorhombic fluid. This provides further evidence in confirmation of the biaxiality of the nematic phase of this copper complex.
