atoms tends towards a tetrahedral environment. The Pd-Cl bond lengths are sur-
prisingly constant. They vary between 2.3462(11) Å for
14d
and 2.357(2) Å and
consists of slightly longer values for
14b
,
c
. As a first conclusion one can say that
the amount of substitutions of the phenyl rings is significantly correlated to the
increasing Pd-P bond lengths, widening of the P1-Pd-P2 bond angle and to high
distortion from the square-planar coordination geometry [56]. Furthermore, the
crystal structures of
14 c
,
d
indicate that in both complexes isopropyl substituents
are located in axial positions above and below the coordination plane. This charac-
