Neodymium chlorid

As so often in this review, Matignon was the first to provide quantitative information, reporting the solubility of neodymium chloride in... 

There is tolerable agreement between the values in Tables XVI and XVH, in such cases as direct or almost direct comparison is possible. Thus, for example, the Russian value of 48.52% by weight for the solubility of neodymium chloride at 30°C may be compared with 49.7% by Hinchey and Cobble, at 25°C. Indeed, if one follows the solubilities reported for neodymium chloride back to Matignon, the values at or near 25°C are all reasonably close together (178, 201, 205, 207, 258, 259). On the question of comparability, it may be remarked here that solubility comparisons are from time to time precluded by the preference of some authors for weight units, and of others for volume concentration units. When densities are also given, then of course interconversion is straightforward, but densities are by no means always available when needed. 

Anhydrous neodymium chloride unites with ammonia gas at low temperature, or if kept in a sealed tube with liquid ammonia, yielding a voluminous rose-coloured powder of composition [Nd(NH3)12]Cl3.

By application of the dimethylsilyl-bridged bisfluorenyl neodymium chloride complex [Me2Si(Ci3H8)2]NdCl (cocatalysts Buli, DIBAH, BuMgCl, BuMgOct) a complete new class of polymers is accessible by the copolymerization of ethylene and BD [307]. By reaction of 1 eq. BD and 2 eq. of ethylene 1,2-cyclohexane units are formed along the polymer chain. More than half of the inserted BD units (53-58 mol %) are involved in the ring closure reaction. The residual non-cyclicized BD units exhibit a nearly identical ratio of trans-1,4- and 1,2-units.

Neodymium carrier 10 mg Nd3+/mL. Dissolve 6.38 g of Nd203 in a beaker with 10 mL of concentrated nitric acid heat if necessary. Transfer solution to flask and dilute to 250 mL with de-ionized water. If neodymium nitrate or neodymium chloride is available, the carrier may be prepared from one of these salts, with the weight of salt recalculated to match the chemical formula.

In most of these systems there is clear evidence for the formation of the reduced ion For example, in NdX2 salts this is on the basis of magnetic studies (3J), and with the praseodymium chloride and bromide phases, from qualitative resistivity measurements and their structural relationships to the neodymium chlorides according to x-ray data. Cryo-scopic data for all the systems listed are also consistent with the formation of a as opposed to solute in dilute solution in MX3 (3, 7).
