E,C,E-coordinating pincer-type ligands (E = heteroatoms
such as N, P, O, S...) are well established for stabilizing numerous
complexes of metals such as tin, platinum and palladium. [1] Beside
that ability however, the coordination chemistry of the ligands
themselves is not well explored. In continuation of our systematic
studies on phosphorus-containing O,C,O-coordinating pincer-type
ligand [2] – 4-t-Bu-2,6-[P(O)(Oi-Pr) ] C H we present here the
2 2 6 2
phosphorus-substituted derivatives 4-t-Bu-2,6-[P(O)(Oi-
-Pr) ] C H P(E)Ph (E = O, S, Se, lone pair) and complexes with

a variety of transition metals.

In recent years, all solid state lithium ion batteries have been
attracting more attention owing to their properties of high power
density and good safety. As an important part of the battery,
inorganic solid state electrolytes (Li La TiO , LLTO) become
3x 2/3-x 3
a significant issue because they present the highest lithium ion
electrical conductivity at room temperature (about 10-3 S.cm-1 for
x = 0.3). [1, 2]
It is well known that the conductivity of LLTO strongly
depends on the exact conditions of sample preparation. Until now
most of inorganic solid-state electrolytes have been obtained by
solid state reaction. As known, this conventional preparation
method needs high sintering temperature and long sintering
time, [3] which result in serious lithium loss during sintering
process and in a particle size increase that is negative for
micro-electrolyte layers in battery applications. As alternatives,
some other synthetic methods have been used to prepare LLTO
ceramics pellets or thin films. [4, 5] Furthermore the lithium content
(x value) and the cooling rate in the sample syntesis play a crucial
role in the structural properties, and then, in the materials
properties as conductivity. [2]
In this sense, this study is focused on the synthesis route,
sintering temperature, cooling rate and crystal stability of the
Li La TiO electrolyte in order to find out a suitable processing
3x 2/3-x 3
conditions to use in Lithium-ion battery systems.
