Ethyl 2-[({[4-amino-5-cyano-6-(methylsulfanyl)pyridin-2-yl]carbamoyl}methyl)sulfanyl]acetate monohydrate
The title compound, C13H16N4O3S2·H2O, crystallizes in a 'folded' conformation with the ester group lying over the carbamoyl moiety, with one solvent water mol-ecule. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯O hydrogen bond, and an N-H⋯O hydrogen-bonding inter-action involving the lattice water mol-ecule. The packing involves N-H⋯N, N-H⋯O, O-H⋯N and O-H⋯O hydrogen bond...

In he title compound, C(13)H(16)N(4)O(3), the pyrazole ring is planar (r.m.s. deviation = 0.054 Å). The pyran ring is not planar; the mean plane makes a dihedral angle of 1.9 (1)° with the pyrazole ring. In the crystal structure, inter-molecular N-H⋯N and N-H⋯O inter-actions lead to a linear chain motif.

The pyran ring of the title compound, C(13)H(18)N(2)O(3), is almost planar (r.m.s. deviation = 0.059 Å). The crystal packing is stabilized by N-H⋯O and N-H⋯N hydrogen bonds.

In the title compound, C(13)H(18)N(2)O(3), the two H atoms of the NH(2) group are engaged in hydrogen bonding with the N atom of the cyano group and with one O atom of the ethoxy-carbonyl group, building a chain parallel to the [100] direction. The N-H⋯N hydrogen bonds assemble the mol-ecules around inversion centres, forming dimers with an R(2) (2)(12) graph-set motif.

In the asymmetric unit of the title compound, C16H14N4O3·C2H6OS, there are two independent main mol-ecules (A and B) and two dimethyl sulfoxide solvent mol-ecules. In mol-ecule A, the pyran ring is in a flattened sofa conformation, with the sp (3)-hydridized C atom forming the flap. In mol-ecule B, the pyran ring is in a flattened boat conformation, with the sp (3)-hydridized C atom and the O a...
