Reaction of isonicotinic acid N-oxide (HINO) with AgClO(4) or AgBF(4) under similar conditions unexpectedly generates two distinct crystalline products {[Ag(3)(INO)(2)(HINO)(2)]center dot(ClO(4))}(n) (1) and {[Ag(INO)]center dot(H(2)O)}(n) (2). Complex 1 consists of a 3-D cationic net with mixed-connected topology and the included perchlorate counterions, whereas 2 has a 3-D neutral open framework (4-connected crb topology) with the accommodation of lattice water. The anion exchange/competition and guest desorption/adsorption behavior have also been thoroughly explored.
