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 are further connected by interwoven Nd–(p-XBP4)–Nd bridges, and yet again by non-coordinated p-XBP4 molecules hydrogen bonded to aqua ligands on the Nd centres.
