Interpenetrated networks from a novel nanometer-sized pseudopeptidic ligand, bridging water, and transition metal ions with CdSO4 topology.

The combination of a new pseudopeptidic ligand, transition
metal ions, and bridging water molecules results in the
formation of [M(m-TBG)(m-H2O)(H2O)2]?2H2O (M: Cu, Co
and H2TBG: terephthaloylbisglycine); both compounds show
rare two-fold interpenetrated three-dimensional cds-nets and
reversible loss of coordinated and lattice water molecules
