2-[1-(Hydroxyimino)ethyl]-2,5,5-tri- methylperhydropyrimidine-butane-2,3-dione monooxime (1/1)

Abstract

The title compound, C9H19N3O C4H7NO2, displays strong intramolecular O?H N [O N 2.6743 (13) AÊ ] and N? H N [N N 2.6791 (15) AÊ ] hydrogen bonds, and strong intermolecular O?H N [O N 2.7949 (15) AÊ ] and N? H O [N O 3.0924 (16) AÊ ] hydrogen bonds. This creates chains of perhydropyrimidine molecules, linked by hydrogen bonds. Each chain is linked to a partner chain, through hydrogen bonds to two butane-2,3-dione monooxime molecules, in a structure reminiscent of a ladder.
