Two infinite complexes {[Cu2(O2CCH3)4](3-tpt)(CH3OH)2} (1) and {[Cu2(O2CPh)4](3-tpt)(C6H6)1.5} (2) were obtained by reactions of 2,4,6-tris(3′-pyridyl)-1,3,5-triazine (3-tpt) with Cu2(O2CCH3)4 and Cu2(O2CPh)4, respectively, which have been structurally established by single-crystal X-ray diffraction. Complex (1) consists of one-dimensional zig-zag chains in its solid state, which can encapsulate methanol molecules; complex (2) consists of one-dimensional helical chains in its solid state, providing large channels which can selectively enclathrate benzene molecules. (1) crystallizes in the monoclinic space group P21/c with a 8.2892(4), b 22.8479(8), c 16.9258(10) Å, β 99.1480(10)°, V 3164.8(3) Å3, and Z 4; (2) crystallizes in the triclinic space group P1 with a 10.7641(8), b 12.0908(8), c 18.9039(12) Å, α 82.514(3)°, β 85.268(2)°, γ 79.746(4)°, V 2395.9(3) Å3, and Z 2. The inclusion selectivity toward aromatic molecules was discussed.
