Crystal structure of 1-methylimidazole 3-oxide monohydrate.


ABSTRACT: 1-Methylimidazole 3-N-oxide (NMI-O) crystallizes as a monohydrate, C4H6N2O·H2O, in the monoclinic space group P21 with Z' = 2 (mol-ecules A and B). The imidazole rings display a planar geometry (r.m.s. deviations = 0.0008 and 0.0002?Å) and are linked in the crystal structure into infinite zigzag strands of ?NMI-O(A)?OH2?NMI-O(B)?OH2? units by O-H?O hydrogen bonds. These chains propagate along the b-axis direction of the unit cell.
