2-Amino-5-oxo-4-(thio­phen-2-yl)-5,6,7,8-tetra­hydro-4H-chromene-3-carbo­nitrile

In the crystal structure of the title compound, inter­molecular N—H⋯N and N—H⋯O hydrogen bonds form a two-dimensional supra­molecular network along the ac plane, contributing to the cohesion of the crystal.

Tris(4-chloro­phen­yl) phosphate

In the title compound, the symmetric phosphate derived from para-chloro­phenol and phospho­ric acid, two of the three aromatic moieties adopt syn-orientation towards the P&z-dbnd;O bond while the last chloro­phenol ring is pointing away from this bond. In the extended structure, C—H⋯O bonds connect the individual mol­ecules into sheets lying perpendicular to the crystallographic b axis.
