Abstract
Abstract The crystal and molecular structure of sodium deoxyinosine monophosphate (5′-dIMP) has been determined by x-ray crystallographic methods. The crystals belong to orthorhombic space group P212121, with a = 21.079(5) A, b = 9.206(3) A and c = 12.770(6) A. This deoxynucleotide shows common nucleotide features namely anti conformation about the glycosyl bond, C2′ endo pucker for the deoxyribose sugar and gauche-gauche orientation for the phosphate group. The sodium ion is directly coordinated to the O3′ atom, a feature observed in many crystal structures of sodium salts of nucleotides.
