摘要

In the course of crystal-engineering experiments, crystals of the hydrated title salt, Na10[Pd2Cl6](C4H9SO3)8·4H2O, were obtained from a water/2-propanol solution of sodium n-butane­sulfonate and sodium tetra­chlorido­palladate(II). In the crystal, sodium n-butane­sulfonate anions and water mol­ecules are arranged in an amphiphilic inverse bilayered cationic array represented by the formula {[Na10(C4H9SO3)8(H2O)4]2+}n. Within this lamellar array: (i) a hydro­philic layer region parallel to the bc plane is established by the Na+ cations, the H2O mol­ecules (as aqua ligands in κNa,κNa′-bridging coordination mode) and the O3S– groups of the sulfonate ions, and (ii) hydro­phobic regions are present containing all the n-butyl groups in an almost parallel orientation, with the chain direction approximately perpendicular to the aforementioned hydro­philic layer. Unexpectedly, the flat centrosymmetric [Pd2Cl6]2− anion in the structure is placed between the butyl groups, within the hydro­phobic regions, but due to its appropriate length primarily bonded to the hydro­philic ‘inorganic’ layer regions above and below the hydro­phobic area via Pd—Clt⋯Na- and Pd—Clt⋯H—O(H)—Na-type (Clt is terminal chloride) inter­actions. In addition to these hydrogen-bonding inter­actions, both aqua ligands are engaged in charge-supported S—O⋯H—O hydrogen bonds of a motif characterized by the D 4 3(9) graph-set descriptor within the hydro­philic region. The crystal structure of the title compound is the first reported for a metal n-butane­sulfonate.
