calculated to be 6.396 Å. Coordination planes of both the palladium
atoms are almost perpendicular to the plane of anthracene moiety.
The palladium-containing ethynyl arms of the molecular “clip” are
not perfectly parallel rather they are slightly pushed outward owing
to steric hindrance among neighboring PEt
