Structure of fortimicin B

Abstract

Abstract.O 3,4,deoxyglucopyranosyl-(1 --, 4)-L-3-amino-1-methoxy-6 methylamino-1,3,6-trideoxy-chiro-inositol, C ~sH3~N 4-O5.3.5H20, 3/, = 347-438, orthorhombic, P2t2t2~, a = 13-966 (2), b = 16.472 (2), c = 9.522 (1) .~,, Z = 4, D x = 1.245 gcm -3. The structure was solved by direct methods. The final R value was 0.078 for 1713 reflexions. The two six-membered rings are in the chair conformation and are bound through the a-linkage. The solvent molecules are hydrogen bonded to each other and to the molecule.
