Methyl 2-(2-amino-1,3-thia­zol-4-yl)-2-[(Z)-methoxy­carbonyl­methoxy­imino]ethano­ate

In the mol­ecule of the title compound, C(9)H(11)N(3)O(5)S, the thia­zole ring is oriented at dihedral angles of 87.33 (3) and 87.18 (3)° with respect to the planar (r.m.s. deviations 0.0136 and 0.0139 Å) methyl ester groups. The dihedral angle between the methyl ester groups is 44.20 (3)°. In the crystal structure, inter­molecular N—H⋯N, N—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules along the a axis, through R (2) (2)(8) and R (2) (2)(22) ring motifs, forming infinite two-dimensional polymeric sheets. π–π Contacts between the thia­zole rings [centroid–centroid distance = 3.536 (2) Å] may further stabilize the structure.
