ABSTRACT: In the title compound, C(20)H(19)N O(2)S(2),the 3Hbenzo-chromene ring system is nearly planar, with a maximum deviation of 0.036?(2)?Å, and the piperidine ring adopts a chair conformation: the bond-angle sum for its N atom is 358.7°. The dihedral angle between the 3H-benzo[f]chromene ring and the piperidine ring is 89.07?(8)°. In the crystal, C-H?O hydrogen bonds lead to [010] C(6) chains and weak aromatic ?-? inter-actions between the fused pyran ring and fused benzene ring of benzochromene [centroid-centroid distance = 3.652?(1)?Å] are also observed.

Sodium piperidine-1-carbodithio-ate dihydrate.

Project description:The asymmetric unit of the title compound, Na(+)·C(6)H(10)NS(2) (-)·2H(2)O, is composed of a sodium cation, a piperidine-dithio-carbamate anion which exhibits positional disorder, and two lattice water mol-ecules.
