Two novel crystal architectures with wire frameworks, [Ag 2 (btc)(im)] n (1) and [Ag 3 (btc)(im)H 2 O] n (2) (btc = 1, 3, 5-benzene tricarboxylic acid, im = imidazole), have been assembled by hydrothermal method and characterized by X-ray diffractions, elemental analysis, fluorescence spectra and thermal gravimetric analyses (TGA), respectively. Using silver sulfate, complex 1 was arranged as "zigzag" chains of silver ions, while using silver nitrate, complex 2 was presented as straight Ag
