Bis(hy­droxy­ammonium) hexa­chlorido­platinate(IV)–18-crown-6 (1/2)

In the title complex, (NH(3)OH)(2)[PtCl(6)]·2C(12)H(24)O(6), the Pt(IV) 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 [PtCl(6)](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 –CH(2)– groups are turned to the outside.
