title: Crystal structure of oxam-yl.
abstract: The title compound, C7H13N3O3S [systematic name: (Z)-methyl 2-di-methyl-amino-N-(methyl-carbamo-yloxy)-2-oxoethanimido-thio-ate], is an oxime carbamate acaride, insecticide and nematicide. The asymmetric unit comprises two independent mol-ecules,AandB. The dihedral angles between the mean planes [r.m.s. deviations = 0.0017 (A) and 0.0016 Å (B)] of the acetamide and oxyimino groups are 88.80 (8)° forAand 87.05 (8)° forB. In the crystal, N/C-H⋯O hydrogen bonds link adjacent mol-ecules, forming chains along theaaxis. The chains are further linked by C-H⋯O hydrogen bonds, resulting in a three-dimensional network with alternating rows ofAandBmol-ecules in thebcplane stacked along thea-axis direction. The structure was refined as an inversion twin with a final BASF parameter of 0.16 (9).
