RESUMO
The title compound, C(6)H(11)N(3)O(3)·0.5H(2)O, has two independent mol-ecules and one mol-ecule of water in the asymmetric unit. The crystal packing is stabilized by inter-molecular N-Hâ¯N, O-Hâ¯O, N-Hâ¯O and C-Hâ¯O hydrogen bonds. These inter-actions form a two-dimensional array in the ab plane with a zigzag motif which has an angle close to 35° between the zigzag planes. The hydrogen bonding can be best described using the graph-set notation as N(1) = C(10)R(2) (2)(10)R(2) (2)(8) and N(2) = R(6) (4)(20)R(2) (2)(8).
RESUMO
The title compound, C(6)H(11)N(3)O(2)S, consists of a roughly planar mol-ecule (r.m.s deviation from planarity = 0.077â Å for the non-H atoms) and has the S atom in an anti position to the imine N atom. This N atom is the acceptor of a strongly bent inter-nal N-Hâ¯N hydrogen bond donated by the amino group. In the crystal, mol-ecules are arranged in undulating layers parallel to (010). The mol-ecules are linked via inter-molecular amino-carboxyl N-Hâ¯O hydrogen bonds, forming chains parallel to [001]. The chains are cross-linked by N(carbazone)-Hâ¯S and C-Hâ¯S inter-actions, forming infinite sheets.
