Molecular-Packing Analysis of Some Glucofuranoimidazolidine Crystals
(International Union of Crystallography, 1987)
Lattice-energy minimization for seven glucofuranoimidazolidine crystals was carried out in the atom-atom approach using an (exp-6-1) form for atom-pair interactions. Molecular rotation and translation and also internal ...
