Crystal and molecular structure of hexakisantipyrineyttrium tri-iodide

Abstract

The structure of the title compound has been determined by single-crystal X-ray diffraction. Crystals are rhombohedral with Z= 3 in a unit cell (based on hexagonal axes) of dimensions: a= 13·896(3), c= 31·986(6)Å, γ= 120°, space group R[3 with combining macron]. The structure was solved by Patterson and Fourier methods and refined by least-squares using 825 observed three-dimensional photographic data to R 0·073. The Y3+ ion is co-ordinated to six antipyrine molecules through the carbonyl oxygen and the molecular symmetry is [3 with combining macron], S6. The angle between the normals to the phenyl ring and the pyrazole ring is 58°.
