The title compound is monoclinic, space group P2 Jc, with a = 4.020 (4), b = 21.491(3), c = 7-410 (4) ,4,, fl = 124.1 (5) °, Z = 4. The structure was solved by Patterson-function and heavy-atom methods from diffractometer X-ray data. The final R value is 0.040. All the atoms lie approximately on the least-squares plane of the imidazoline ring....

The crystal structure of Cl3Ht6N20 5 has been solved by direct methods. Crystal data are a -- 9.033 (1), b -- 10.097 (1), c -- 7.155 (1)A, fl= 105.92 (1) °, Z -- 2, space group P21 (from statistics). The final R value for 1246 independent reflexions was 0.068. The glucofurano- imidazolidine group adopts a cis form of coupling with a dihedral...
