In the title compound, C21H21O5PS·H2O·CH2Cl2, the phosphonium–sulfonate zwitterion has the acidic H atom located on the P atom rather than the sulfonate group. The S—O bond lengths [1.4453 (15)–1.4521 (14) Å] are essentially equal. In the crystal, the water molecules bridge two zwitterionsviaOwater—H...Osulfonatehydrogen bonds into a centrosymmetric dimer. The dimers are further linked by weak CAryl—H...Osulfonatehydrogen bonds into chains extending along [100]. The PH+group is not involved in intermolecular interactions.

The asymmetric unit of the title compound, C10H9N2 +·0.5C2O4 2−·C2H2O4·H2O, consists of a 2,2′-bipyridinium cation, half an oxalate dianion, one oxalic acid and one water molecule. One N atom in 2,2′-bipyridine is unprotonated, while the second is protonated and forms an N—H...O hydrogen bond. In the crystal, the anions are connected with surrounding acid molecules and water molecules by strong near-linear O—H...O hydrogen bonds. The water molecules are located between the anions and oxalic acids; their O atoms participate as donors and acceptors, respectively, in O—H...O hydrogen bonds, which form sheets arranged parallel to the ac plane.

From an aqueous solution of racemic 2,3-dibromosuccinic acid and (R)-1-phenylethanamine, crystals of the title compound, C8H12N+·0.5C4H2Br2O4 2−·0.5C4H4Br2O4·H2O, were obtained in almost quantitative yield. The structure contains both enantiomers of the starting material, dibromosuccinic acid. The S,S enantiomer is present as a dianion and the R,R enantiomer as the neutral acid; both of these components lie on twofold rotation axes. The structure features a complex two-dimensional network of hydrogen bonds.

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.
