was reacted further with an additional amount of KCl, the
reaction yielded K2ZnCl4 [44, 45] (Fig. 8).
The formation of K2ZnCl4 from the intermediate phase
does not prove the single phase nature of the intermediate,
but on the other hand, there is no need to argue otherwise;
final certainty about this could probably only be achieved
by structure solution from the powder pattern for which,
however, the data quality is clearly insufficient, again due
to the limitations associated with the mechanochemical syn-
thesis.

The existence of new (metastable) phases in ternary sys-
tems may be expected, because the enthalpy gain from the
synproportionation of two binary chlorides to a ternary
system is rather small (ϳ0.6 - 20 kJ molϪ1, usually much
less than 1 % of the total lattice enthalpy). But enthalpy
values have significance only at 0 K; at higher temperatures,
the Gibbs enthalpy has to be considered as the sole
criterion for stability („high” relative to 0 K) [52].
A small endothermic formation enthalpy overruled by a
sufficient negative entropy term TΔS can still result in a
negative Gibbs enthalpy: the synproportionation enthalpy
for K2CoCl4 from KCl and KCoCl3 according to Eq. (4) is
almost zero (0.6 kJ molϪ1)! Nevertheless the reaction pro-
ceeds to K2CoCl4, due to the considerable entropy gain pro-
vided by the transition from linked to isolated coordination
polyhedra [52].

This study proves, that ball milling is a versatile and use-
ful tool in solid state chemistry, especially as a preparative
method. Mechanochemical synthesis gave easy access to a
number of known and previously unknown ternary halides,
and it is expected that also numerous other compounds will
be accessible via related pathways. The disadvantages of the
method with respect to structural investigation are the small
particle sizes and high defect concentrations induced by the
ball milling, which seriously impedes structural analysis. It
is typically not possible to produce single crystals suffic-
iently big for structural analysis. The quality of the powder
diffraction data is also insufficient for structure solution, so
that only comparison to known structure types can give
indications with respect to the structure of new compounds.
However, the results of our investigations may induce work
to produce higher quality samples of some of the phases
described and thus further promote knowledge on these
and related compounds. On the other hand, the very weak-
ness of the mechanochemical synthesis pathway turns into
a strength, when the products of this preparation method
are to be converted to other compounds, such as the multin-
ary hydrides discussed in the introduction. Work in this di-
rection is going on in our laboratory, and possibly, novel
hydride storage materials can emerge from this line of work.
