DIVERSITY OF LINKING MODES BY N,N'-P-PHENYLENEDIMETHYLENEBIS(PYRIDIN-4-ONE) [P-XBP4] IN THE NOVEL LINKED LANTERN FRAMEWORK COMPLEX 2(P-XBP4)(6)(H2O)(4)](P-XBP4)(H2O)(3)(CLO4)(6))(N)

The title compound has a complex framework structure in which pairs of Nd atoms are linked by four p-XBP4 ligands to form 'lanterns' which a re further connected by interwoven Nd-(p-XBP4)-Nd bridges, and yet aga in by non-coordinated p-XBP4 molecules hydrogen bonded to aqua ligands on the Nd centres.
