title: Crystal structure of O-ethyl N-(eth-oxy-carbon-yl)thio-carbamate.
abstract: The title compound, C6H11NO3S, provides entries to novel carbamoyl disulfanes and related compounds of inter-est to our laboratory. The atoms of the central O(C=S)N(C=O)O fragment have an r.m.s. deviation of 0.1077 Å from the respective least-squares plane. While several conformational orientations are conceivable, the crystal structure shows only the one in which the carbonyl and the thio-carbonyl moieties are anti to each other across the central conjugated C-N-C moiety. Pairs of 2.54 Å N-H⋯S=C hydrogen bonds between adjacent mol-ecules form centrosymmetric dimers in the crystal.
