Figure 3
(a) Crystal structure of glipizide. A chain of hydrogen bonds runs into the page. Double-headed arrows indicate the two vibrational terms present along b. (b) R22(10) hydrogen-bond network in glipizide, and the A polymorph of acetohexamide (Stephenson et al., 1997BB22). (c) Hydrogen-bond network in 1-isopropyl-3-(4-(3-chlorophenylthio)-pyrid-3-yl)sulfonylurea (Dupont et al., 1979BB7), and in the B polymorph of acetohexamide (Stephenson, 2000BB21). For (b) and (c), the single-headed arrows arrows indicate the fragment orientation.
