In the title complex, (NH3OH)2[PtCl6]·2C12H24O6, the PtIV atom is coordinated by six chloride anions in a slightly distorted octa­hedral geometry. The Pt—Cl bond lengths are comparable to those reported for other hexa­chlorido­platinate(IV) species. The hy­droxy­ammonium groups act as linkers between the [PtCl6]2− anion and the crown ether mol­ecules. The anion is linked to two hy­droxy­ammonium cations via O—H...Cl hydrogen bonds and each hy­droxy­ammonium moiety is linked to a crown ether mol­ecule by hydrogen bonds between ammonium H atoms and 18-crown-6 O atoms. The crown ether mol­ecules have the classic crown shape in which all O atoms are located in the inner part of the crown ether ring and all –CH2– groups are turned to the outside.

The title compound, C16H12N2O, exists in the crystalline state as the 5-imino-3,4-di­phenyl­-1H-pyrrol-2-one tautomer. The dihedral angles between the pyrrole and phenyl rings are 35.3 (2) and 55.3 (2)°. In the crystal, inversion dimers linked by pairs of N—H...N hydrogen bonds generate a graph-set motif of R22(8) via N—H...N hydrogen bonds.

In the title compound, C16H11NO2·C5H9NO, the dihedral angles between the male­imide and phenyl rings are 34.7 (2) and 64.8 (2)°. In the crystal, the 2,3-di­phenyl­male­imide and 1-methyl­pyrrolidin-2-one mol­ecules form centrosymmetrical dimers via pairs of strong N—H...O hydrogen bonds and π–π stacking inter­actions between the two neighboring male­imide rings [centroid–centroid distance = 3.495 (2) Å]. The dimers are further linked by weak C—H...O and C—H...π hydrogen bonds into a three-dimensional framework.
