Figure 2 A portion of the one-dimensional hydrogen bonded ladder structure which consists of two antiparallel strands of singly N–H⋯O bonded barbiturate molecules, which are bridged by dioxane molecules, N–H⋯O(dioxane)O⋯H–N. The structure is viewed parallel to the c-axis. O and H atoms involved in hydrogen bonding ar drawn as balls. |
