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

The combination of a new pseudopeptidic ligand, transition metal ions, and bridging water molecules results in the formation of [M((mu)-TBG)((mu)-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.
