Ammonium tosylate, hydrated metal tosylates [Ca(H2O)(4)(p-SO3C6H4CH3)(2)] and [M(H2O)](6)(p-SO3C6H4CH3)(2) (M = Mg, Mn, Fe, Co, Ni and Zn) and [M(H2O)(2)(15-crown-5)](p-SO3C6H4CH3)(2) (M = Mn, Co and Zn) have been crystallised from aqueous media and their structures determined by X-ray crystallography. The ammonium complex is an anhydrous species with a complex hydrogen bonding array. The structure of the calcium complex shows the tosylate is bound directly to the calcium centre through the SO3 moiety, while the remaining isomorphous complexes all have a hexahydrated metal centre involved in a complex hydrogen bonded network through M-OH2. . .O-S interactions. The crown ether containing compounds [M(H2O)(2)(15-crown-5)(p-SO3C6H4CH3)(2)] (M = Mn, Co and Zn) have crown-encapsulated M(H2O)(2)(2+) ions with tosylate ions involved in hydrogen bonding bridging the cations in a one-dimensional polymer.
