摘要

Two series of ten 3D porous coordination polymers (PCPs), [Ag(L-434)](BF4)(DMF)(2) (1 center dot BF4 center dot DMF), [Ag-(L-434)](BF4)(CH3CN)(2) (1 center dot BF4 center dot CH3CN), [Ag(L-434)](BF4)(DMA)(CH3OH) (1 center dot BF4 center dot DMA/CH3OH), [Ag(L-434)](ClO4)(DMF)(2) (1 center dot ClO4 center dot DMF), [Ag(L-434)](CF3SO3)(DMF) (1 center dot CF3SO3 center dot DMF), [Ag(L-434)](ClO4)(CH3CN)(2) (1 center dot ClO4 center dot CH3CN), [Ag(L-434)](PF6)(CH3CN)(2) (1 center dot PF6 center dot CH3CN), [Ag(L-434)] (CH3SO3)(DMA) (1 center dot CH3SO3 center dot DMA), [Ag(L-434)](CF3SO3)(DMA) (CF3SO3-DMA), and [Ag-2(L-434)(2)](BF4)(2)(CH3OH)(2) (2 center dot BF4 center dot CH3OH), have been prepared via assembling 3,5-bis(4-pyridy1)-4-(3-pyridy1)-1,2,4-triazole (L-434) with Ag(I) salts in different solvent media. All these PCPs possess 3D porous cationic frameworks, exhibiting irl topology for 2 center dot BF4 center dot CH3OH and sra topology for others (1 center dot anion center dot solvent) with the same point symbol of (4(2).6(3).8). Solvent-induced structural transformations between the topo-isomeric 1 center dot BF4 center dot solvent and 2 center dot BF4 center dot CH3OH show drastic deformations of the 3D host frameworks and concomitant solvent exchanges. Three cycles of anion-induced structural conversions involving 1 center dot anion center dot DMF, 1 center dot anion center dot CH3CN, and 1 center dot anion center dot DMA isoreticular structures are also observed, in which the mother frameworks are almost unchanged during the anion exchanges. These two types of structural transformations occur upon different external stimuli (solvent and anion), which are accompanied by significant changes in the shape of channels and the volume of voids.
