Abstract:
The hydro-thermal reaction of Zn(CH(3)COO)(2), NaOH and l-cysteic acid produced the title compound, [Na(2)Zn(C(3)H(5)NO(5)S)(2)](n). The Zn(II) cation is situated on an inversion centre and is in a distorted octa-hedral environment, being chelated by two deprotoned l-cysteic acid ligands through two amino N atoms and two carb-oxy-lic O atoms, with the two axial positions occupied by two carb-oxy-lic O atoms from two other l-cysteic acid ligands. Each l-cysteic acid ligand bridges five Na(I) ions via its sulfonate group and two Zn(II) ions via its carboxyl group, forming a three-dimensional framework. Weak N-H⋯O hydrogen bonding is observed in the crystal structure.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

Ions as Acids and Bases
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:
