Crystal Structure of Gadolinium Formate, Gd(OOCH)3

This is the authors' abstract. We don't add key points for this paper.

The crystal structure of gadolinium formate has been studied by means of Laue, rotation, and powder x-ray patterns. It has a rhombohedral lattice. The unit cell, a0=6.17A, a=115° 30′, contains one molecule, Gd(OOCH)3. Density—(calculated) 3.85, (Berman balance) 3.77. By taking into consideration the symmetry of special positions all space groups except D37—R32 and C3v5—R3m can be excluded. A structure has been found in the latter group which yields excellent agreement of calculated and observed intensities.
