Fig. 2. Schematic representation of the structural transformation of [Gd(H4nmp)(H2O)2]Cl·2H2O (1, left) into [Gd2(H3nmp)2]·xH2O (2, right) (x = 1 to 4) at high temperatures and humidity. The figure emphasizes the release of the Cl– anion as hydrochloric acid and the irregular rearrangements of the 2∞[Gd2(H3nmp)2] layers.
