The solvent effects on suprachannel formation via a molecular array of 2D networks were studied. The basic structure of the [Ag3L2](X)3 (X鈥?/sup> = NO2鈥?/sup>, NO3鈥?/sup>) 2D network consists of hexagonal (Ag6L6) motifs formed via self-assembly of Ag(I) with C3-tridentate N-donors. The 2D networks are arranged in an eclipsed mode in aqueous solution, thus forming suprachannels (5.2 脳 7.3 脜2, 6.2 脳 7.7 脜2) of [Ag3L2(H2O)2](X)3, whereas they are arranged in a staggered abab... mode in nonaqueous solution, thus forming semisuprachannels (3.1 脳 5.1 脜2) of [Ag3(NO3)2L2](NO3). The suprachannel structure of [Ag3L2(H2O)2](NO3)3 is soluble in methanol; contrastingly, the semisuprachannel structure of [Ag3(NO3)2L2](NO3) is insoluble in that solvent. In the present study, significant differences in molecular recognition and anion exchangeability between [Ag3L2(H2O)2](NO3)3 and [Ag3(NO3)2L2](NO3) were found.
