title: Methyl 2-(2-amino-1,3-thia-zol-4-yl)-2-[(Z)-methoxy-carbonyl-methoxy-imino]ethano-ate.
abstract: In the mol-ecule of the title compound, C(9)H(11)N(3)O(5)S, the thia-zole 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, inter-molecular N-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules 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 thia-zole rings [centroid-centroid distance = 3.536 (2) Å] may further stabilize the structure.
