Crystal structure of 1-methyl-3-([2,2-dimethyl-4,6-dioxo-1,3-dioxane-5- ylidene]methyl)urea

Abstract

The crystal structure of 1-Methyl-3-([2,2-dimethyl-4,6-dioxo-1,3-dioxane-5- ylidene]methyl)urea (C9H12N2O5) has been determined by single crystal X-ray diffraction analysis. The crystals are monoclinic, a = 5.3179(2), b = 18.6394(6), c =10.8124(3) Å, β = 100.015(2), Z = 4, sp. gr. P21/c, R = 0.0381 for 2537 reflections with I > 2σ(I). Except for C(CH3)2 group, the molecule is planar. The structure is stabilized by inter- and intramolecular N-H.O hydrogen bonds and weak C-H.O interactions. © 2013 Pleiades Publishing, Inc.
