title: Bis(hy-droxy-ammonium) hexa-chlorido-platinate(IV)-18-crown-6 (1/2).
abstract: In the title complex, (NH3OH)2[PtCl6]·2C12H24O6, the Pt(IV) atom is coordinated by six chloride anions in a slightly distorted octa-hedral geometry. The Pt-Cl bond lengths are comparable to those reported for other hexa-chlorido-platinate(IV) species. The hy-droxy-ammonium groups act as linkers between the [PtCl6](2-) anion and the crown ether mol-ecules. The anion is linked to two hy-droxy-ammonium cations via O-H⋯Cl hydrogen bonds and each hy-droxy-ammonium moiety is linked to a crown ether mol-ecule by hydrogen bonds between ammonium H atoms and 18-crown-6 O atoms. The crown ether mol-ecules 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.
