| Abstract: | The semi-rigid ligand 1,4-bis((3,5-dimethylisoxazol-4-yl)methyl)benzene (bisox) reacts with a range of silver(i) salts to give products in which the anions dictate the structure. The reactions with AgNO3and AgO2CCF3both lead to compounds in which the anions are coordinated to the silver centres. Thus, the structure of [Ag2(NO3)2(bisox)] 1contains helical silver-nitrate chains that are linked into sheets by bridging bisox ligands, whereas the structures of [Ag(O2CCF3)(bisox)]·0.5X (2a, X = MeOH; 2b, X = MeCN) consist of sheets in which Ag2(μ-O2CCF3)2dimers act as 4-connecting nodes. In these structures bisox adopts the S-conformation, with the nitrogen donor atoms antito each other. The reactions of bisox with AgClO4and AgBF4in methanol give the compounds [Ag2(bisox)3]X2(3, X = ClO4; 5, X = BF4), the structures of which contain triply-interpenetrated sheets with Borromean links and ligands in the S-conformation. Recrystallisation of these compounds from acetonitrile–diethyl ether gives [Ag2(bisox)3]X2·xEt2O (4, X = ClO4, x= 1; 6, X = BF4, x= 1.2). The structures of 4and 6contain similar triply-interpenetrated sheets to those in 3and 5, though these are sandwiched between sheets of discrete Ag2(bisox)3cages, in which the bisox ligands are in the C-conformation, with the nitrogen donor atoms synto each other. Diethyl ether molecules project through the faces of the cages and template cage formation. Both 4and 6lose diethyl ether on heating in vacuum, and convert into 3and 5, respectively. This solid state transformation requires a change in conformation of half the bisox ligands, with conversion of 6into 5occurring more readily than conversion of 4into 3. The reactions of bisox with AgPF6and AgSbF6in methanol give mixtures of products from which [Ag(bisox)2]X·0.5bisox (7, X = PF6; 8, X = SbF6) can be isolated. Both 7and 8have structures containing one-dimensional chains, in which the bisox ligands adopt C-conformations and interconnect distorted tetrahedral silver centres in a pairwise manner generating macrocycles. Additional uncoordinated bisox molecules lie within half of these macrocyclic rings. Recrystallisation of the crude AgSbF6/bisox reaction mixture from acetonitrile–diethyl ether gives [Ag(bisox)2]SbF69, the structure of which consists of a triply-interpenetrated flattened diamondoid network. A similar structure was observed for [Ag(bisox)2]CF3SO310, which is formed from the reaction of AgO3SCF3and bisox in methanol. [ABSTRACT FROM AUTHOR] |
