Abstract:
Monomeric and polymeric 1:2 complexes of a novel calix4]arene-tetraphosphineoxide with Co(II) or Ni(II) nitrates were synthesized
and analyzed by the X-ray method. In the monomeric complexes each metal cation is coordinated by two bidentate NO3-ligands as well as by two proximal P=O groups at the calixarene skeleton. In the nickel metallopolymer one sort of the cations
is bound by the two proximal P=O-groups but other cations link neighboring calixarene molecules through Р=О···Ni···O=P chains.
The complexes possess molecular cavities or channels filled by solvent molecules.
