Chemical compound
Americium(III) chloride
or
americium trichloride
is the
chemical compound
composed of
americium
and
chlorine
with the
formula
AmCl
3
. This salt forms pink
hexagonal
crystals.
In the solid state each americium atom has nine chlorine atoms as near neighbours, at approximately the same distance, in a tricapped trigonal prismatic configuration.

The hexahydrate has a monocline crystal structure with: a = 970.2 pm, b = 656.7 pm and c = 800.9 pm; β = 93° 37'; space group:
P

Reactions
[
edit
]
An americium(III) chloride
electrorefining
method has been investigated to separate mixtures of
actinides
, since the
standard Gibbs free energy of formation
of americium(III) chloride is much different than the rest of the actinide chlorides.
[6]
This can be used to remove americium from
plutonium
by melting the crude mixture together with salts such as
sodium chloride
.
