Self‐assembly of AgClO 4 with 1,2,3‐tris(isonicotinoyloxy)benzene (L) in a mixture of ethanol and acetone in a 1:1 volume ratio in refrigerator afforded concomitantly two kinds of thin‐ and block‐shaped colorless crystals consisting of {[Ag(L)]ClO 4 ·0.5CH 3 CH 2 OH} n and {[Ag(L)]ClO 4 ·0.5CH 3 CH 2 OH·2Me 2 CO} n , respectively, in a 3:2 ratio. By contrast, self‐assembly at room temperature yielded thin crystals exclusively. At 5 °C, in particular, the self‐assembly in 3:1 and 1:2 ethanol/acetone solutions yielded thin‐ and block‐shaped crystals, respectively, suggesting that discrimination of the two products can be controlled by the solvent volume ratio and crystallization temperature. The products' crystal structures and physicochemical properties were fully characterized by means of single‐crystal X‐ray diffraction measurement, thermal analysis, and infrared (IR) data.
