摘　　要：A new supramolecular self-assembly [Li(H2 O)2]2[(H2 O@Me10 CB[5])][PtC l6]·7 H2 O(1, Me10 CB[5] = decamethylcucurbit[5]uril), has been successfully constructed with Me10 CB[5] and [PtCl6]^(2-) anion in the presence of lithium cation(Li+). Single-crystal X-ray diffraction study reveals that compound 1 crystallizes in monoclinic space group P21/n with a = 11.1681(18), b = 28.5425(4), c = 18.9342(3) ?, β = 99.0143(15)°, V = 5961.02(16) ?~3, Z = 4, F(000) = 3224, μ = 2.714 mm^(-1), R = 0.0470 and wR = 0.1076(I > 2σ(I)). In the supramolecular self-assembly, two of the portal carbonyl oxygen atoms of Me10 CB[5] are coordinated to Li+ cation, yielding a "half-open" molecular capsule. Then adjacent molecular capsules are connected with each other through hydrogen-bonding to form a one-dimensional(1 D) supramolecular chain structure. The [PtCl6]^(2-) anions are fixed on one side of the 1 D supramolecular chain through supramolecular interactions. The thermal stability, electronic valence and morphology of compound 1 are also investigated.
