Er111 complexes with 1 2 stoichiometries are isolated by reaction of the sodium salts of the two oligothiophene ligands with erbium chloride under anhydrous conditions. No analytical data are reported to prove this stoichiometry, but both compounds Na[Er(83a)2] and Nas [Er(83b)2] display the 1.54 pm emission in anhydrous pyridine upon excitation at 353 nm. The emission intensity of [Er(83a)2r is comparable to the fluorescence intensity of [Er(8-Q)3] recorded under the same experimental conditions, while emission intensity of the pentathiophene complex is about half that. This is explained by the more efficient triplet state production in shorter oligothiophenes than in longer ones (Destri et al., 2003).

Acetals Various lanthanide chlorides are efficient catalysts for acetalization of aldehydes by methanol. Lanthanum chloride and cerium chloride are satisfactory for aliphatic aldehydes, but erbium chloride and ytterbium chloride are generally superior, particularly for aromatic and bicyclic aldehydes. Addition of trimethyl orthoformate as a water scavenger allows use of the commerically available hydrated forms of the salts. Acetals can be obtained in 80-100% yield from reactions conducted for 10 minutes at 25°.

In another series of studies of the soluble lanthanide chlorides, rats were fed gadolinium, samarium, terbium, thulium, ytterbium, praseodymium, neodymium, lutetium, europium, dysprosium, holmium, and erbium chloride in their diet at doses of 0, 5, 50, and 500 mg kg day for 12 weeks. Only ytterbium chloride caused any significant effect, with the 500 mg kg dose causing gastric hemorrhages. The other lanthanides caused no adverse effects at the maximum 500 mg kg dose. 

Smolyakova and Serebrennikov [78SMO/SER] measured the enthalpy change of the reaction between an aqueous solution of erbium chloride and Na2Se03(cr). The description of the experiments and calculations is somewhat meagre. Their data have been reevaluated as described in Appendix A and yielded the result Af//° (Er2(Se03) r8H20, am, 298.15 K) = -(5176 11) kJ moP. ...
