The asymmetric unit of the title compound, dipotassium bis[hexaaquanickel(II)] tris(μ2-methylenediphosphonato)tripalladium(II) hexahydrate, K2[Ni(H2O)6]2[Pd3{CH2(PO3)2}3]·6H2O, consists of half a {[Pd{CH2(PO3)2}]3}6−anion [one Pd atom (4e) and a methylene C atom (4e) occupy positions on a twofold axis] in a rare `handbell-like' arrangement, with K+and [Ni(H2O)6]2+cations to form the neutral complex, completed by three solvent water molecules. The {[Pd{CH2(PO3)2}]3}6−units exhibit close Pd...Pd separations of 3.0469 (4) Å and are packedviaintermolecular C—H...Pd hydrogen bonds. The [KO9] and [NiO6] units are assembled into sheets coplanar with (011) and stacked along the [100] direction. Within these sheets there are [K4Ni4O8] and [K2Ni2O4] loops. Successive alternation of the sheets and [Pd{CH2(PO3)2}]3units parallel to [001] produces the three-dimensional packing, which is also supported by a dense network of hydrogen bonds involving the solvent water molecules.

The asymmetric unit of the title compound, 3C10H8N2·2C7H7NO2, consists of three molecules of 4,4′-bipyridine (bpy) and two molecules of 3-aminobenzoic acid (bza). Two molecules of bza and two molecules of bpy are connectedviaO—H...N, N—H...N and N—H...O hydrogen bonds, forming forming infinite double-stranded zigzag chains along thecaxis. The third molecule of bpy is linked to the chain by weak C—H...O interactions. Adjacent chains are linked via π–π interactions [centroid–centroid distances = 3.759 (3)–3.928 (3) Å] involving the pyridine rings of bpy molecules, resulting in a sheet-like structure parallel to (100). These sheets are stackedviaC—H...π interactions, resulting finally in the formation of a three-dimensional supramolecular structure.

In the title compound, [Cu2(OH)2{C12H7N2(PO3C2H5)}2(H2O)2]·7H2O, two Cu2+cations are bridged by two hydroxide groups, forming a centrosymmetric binuclear complex. Each Cu2+cation is further coordinated by the N atoms of a bidentate ethyl (1,10-phenanthrolin-3-yl)phosphonate anion and a water molecule in a square-pyramidal geometry. In the crystal, a network of O—H...O hydrogen bonds involving the P(O)(O−)(OEt) groups, bridging hydroxyl groups, coordinated and uncoordinated water molecules generates a three-dimensional supramolecular structure. The ethyl group exhibits disorder and was modelled over three sites with occupancies of 0.455, 0.384 and 0.161.

The flexible oxyacetate group bound to a methylene C atom of the HOABDC2−ligand links the MnIIcentres into –Mn—O—C—O—Mn– chains, and the carboxylate group bound directly to the benzene ring extends the chains into two-dimensional layers which lie parallel to the (010) plane and present herringbone patterns. Intermolecular O—H...N and C—H...O hydrogen bonds connect the layers into a three-dimensional supramolecular structure.
