The cover picture shows four compounds. Compound 1 displays a 1D polymeric chains. In compound 1, the Gd III atom is nine‐coordinated by six oxygen atoms from the carboxylate group (O1,O1B,O2,O2A,O2B,O2C), two oxygen atoms from the coordinated water molecules (O3,O3B) and one chlorine atom, displaying a tricapped trigonal prismatic geometry. These 1D chains are connected by coordinated water and compound ligand via hydrogen‐bonding interactions into a 3D supramolecular network. Compounds 2–4 are mononuclear. In compound 2 , each Gd III atom is nine‐coordinated by four oxygen atoms from the carboxylate groups and five oxygen atoms of the coordinated water molecules. Adjacent [Gd(tzpya) 2 (H 2 O) 5 ]Cl4H 2 O molecules are linked together through hydrogen‐bonding interactions to generate a 3D network structure. In compound 3 , each Gd III atom is nine‐coordinated by three oxygen atoms from the carboxylate group and six oxygen atoms from the coordinated water molecules, displaying a tricapped trigonal prismatic geometry. The molecules of 3 are interlinked by intermolecular hydrogen bonds, forming a 3D supramolecular network structure. In compound 4 , each Gd III atom is eight‐coordinated by six oxygen atoms from the coordinated water molecules and two oxygen atoms from the carboxylate groups, generating a distorted octahedral geometry. In the crystal of 4 , the adjacent [Gd(pmtza) 2 (H 2 O) 6 ]2H 2 OCl molecules are linked through several kinds of hydrogen bonding interactions, generating a three‐dimensional network. et al. on page 1112ff.
