Abstract:
Halogen bonding (XB) has
been used to assemble tetrakis(4-pyridyl)
pentaerythritol (tetradentate XB
acceptor) with different alpha,omega-diiodoperfluoroalkanes
(bidentate XB donors)
or tetrakis(4-iodotetrafluorophenyl)-
pentaerythritol (tetradentate XB
donor). The remarkable linearity of the
XB formed, the rodlike character of
alpha,omega-diiodoperfluoroalkanes and the mutual complementarities of pentaerythritol
partners, translate the three-dimensional
character of the XB acceptor
into open primary networks, which interpenetrate to avoid the presence of
voids and to ensure segregation of the
modules. Two-dimensional (2D) square
4^4 layers (sql) with fourfold and fivefold
interpenetration, as well as an
eightfold diamondoid network (dia) of
class Ia and a remarkable tenfold dia
network of class IIIa, have been obtained.
