A vessel whose volume was 1.25 L was filled with 0.0125 mol of lanthanum(III) chloride, LaCls, and 0.0250 mol H2O. After the mixture came to equilibrium in the closed vessel at 619°C, the gaseous mixture was removed and dissolved in more water. 

The bicycUc polyethers give rise to complex structures. With lanthanum chloride and Bicy(4,2B,2B), the adduct corresponds approximately to a 1 1 stoichiometry, but a crystalline product is obtained only in the presence of water. The crystal structure analysis shows that partial hydrolysis takes place. In this, the behaviour is reminiscent of the 2 1 TEA complexes with 15C5. Indeed, the unit cell contains a pseudo-centrosymmetric dimer [LaCl(Cl,OH)L]2 with an OH Cl hydrogen bond across the centre of symmetry one site is occupied by Cl in one half and by OH in the other half. The ligand in this structure has an approximate twofold axis of symmetry. The O atoms form an end-capped trigonal prism around La(III) and the metal ion lies in the mean plane formed by the O atoms of the aliphatic unsubstituted chain. The other bicyclic polyether, Bicy(4B,2B,2B), forms 3 2 complexes with lanthanum nitrate. The asymmetric unit contains two dinitrato cations [La(N03)2L] and one pentanitrato anion [La(N03)5(Me0H)] . The La(III) ion is 11-coordinate in the anion and one of the cations, in which there is one bidentate and one monodentate nitrate ion. It is 12-coordinate in the other cation.
